Master Chief Respect Thread *WIP*

[SgCombine]

Thought it'd be nice to have a thread to grab useful feats/calcs/pics/etc for the Chief.

14 years old - After Augs, without Power Armor feats

Overview
Can lift x3 his own body weight
Can run at up to 55 kph (34 mph)
Reaction time under 20 milliseconds
Can see in the dark
Tears titanium with bare hands

"Your Spartans can run at bursts of 55 KPH," he explained. "Kelly can run a bit faster, I think. They will only get faster as they adjust to the 'alterations' we've made to their bodies. They can lift 3 times their body weight- which, I might add, is almost double the norm due to their increased muscle density. And they can virtually see in the dark.

The Sergeant eyed John, then the ODSTs. “You’re all so eager to fight, get in the ring and go to it.” “Sir!” John said. He went to the boxing ring, slipped through the ropes, and stood there waiting. This was starting to make sense. It was a mission. John had received orders from a superior officer, and the four men were now targets.
The big ODST pushed through the ropes and the others gathered to watch. “I’m going to rip you to pieces, meat,” he grunted through clenched teeth. John sprang off his back foot and launched his entire weight behind his first strike. His fist smashed into the man’s wide chin. John’s left hand followed and impacted on the soldier’s jaw. The man’s hands came up; John stepped in, pinned one of the man’s arms to his chest, and followed through with a hook to his floating ribs. Bones broke. The man staggered back. John took a short step, brought his heel down on the man’s knee. Three more punches and the man was against the ropes . . . then he stopped moving, his arm and leg and neck tilted at unnatural angles. The three other men moved. The one with the bloody nose grabbed an iron bar. John didn’t need orders this time. Three attackers at once—he had to take them out before they surrounded him. He might be faster, but he didn’t have eyes in the back of his head. The man with the iron bar swung a vicious blow at John’s ribs; John sidestepped, grabbed the man’s hand, and clamped it to the bar. He twisted the bar and crushed the bones of his attacker’s wrist. John snapped a side kick toward the second man, caught him in the groin, crushing the soft organs and breaking his target’s pelvis. John pulled the bar free—whipped around and caught the third man in the neck, hitting him so hard
the ODST was propelled over the ropes. “At ease, Number 117,” Chief Petty Officer Mendez barked. John obeyed and dropped the bar. Like the pin, it seemed to take too long for the impromptu weapon
to hit the deck.
The ODSTs lay crumpled on the ground, either unconscious or dead.

Beats 4 ODSTs right after his surgery, killing 2 in the process.

In the center stood a concrete bunker. Three men in the primitive Mark I power armor stood on top. Six more stood evenly spaced around the perimeter. A red banner had been planted in the center of the bunker.
“Capture the flag?” Dr. Halsey asked. “Past all that heavy armor?” “Yes. The trainers in those exoskeletons can run at thirty-two KPH, lift two tons, and have a thirtymillimeter
minigun mounted on self-targeting armatures—stun rounds, of course. They’re also equipped with the latest motion sensors and IR scopes. And needless to say, their armor is impervious to standard
light weapons. It would take two or three platoons of conventional Marines to take that bunker.”

John landed, turned, braced, and kicked one guard. The man landed in a heap... 8 meters away

Halo: Fall of Reach pg.
72 paperback

The guard was wearing a suit that probably weighed around a ton considering how much bulkier it was than the armor SII's wear.

The last guard on the bunker turned to fire at John. Halsey gripped the edge of her chair. "He's at point blank range! Even stun rounds can kill at that distance! As the guard's gun fired, John sidestepped. The stun rounds slashed through the air, a clean miss. John grabbed the weapon's armature-twisted-and with a screech of stressed metal, wrenched it free of the exoskeleton.

Dodge's stun rounds and tears metal (titanium possibly) with his tear hands.

"What are their reaction times?"
"Almost impossible to chart. We estimate it at 20 miliseconds," Mende replied. He shook his head, then added, "I believe it is significantly faster in combat situations, when their adrenaline is pumping"

Dr. Halsey marveled at what a spectacular specimen he [John-117] had grown into. Fourteen years old and he had the body of a eighteen-year-old Olympic athlete, and a mind equal to any Naval Honors graduate.

Chief in MJOLNIR Mark IV Power Armor feats

Overview
Strength increased by x2
Reaction time increased by x5 (less than 4 milliseconds)
Bullet proof armor
Can jump 3 meters high

"He stood just over 2 meters tall and weighed in at 130 kilos of rock-hard muscle and iron-dense bone."

Halo: Fall of Reach
pg. 217 paperback

"More importantly," Dr. Halsey said, "the armor's inner structure is composed of a new reactive metal liquid crystal. It is amorphous, yet fractally scales and amplifies force. In simplified terms, the armor doubles the wearer's strength, and enhances the reaction time of a normal human by a factor of 5"

Halo: Fall of Reach
pg. 115 paperback

He can lift 390 kg (860 pounds) without armor. In armor, it doubles to at least 780 kg (1720 pounds).

It also enhances his reaction time x5, putting his reaction time roughly 4 milliseconds in the first power armor he's given at 14 years old. As the previous quote mentions, in a combat scenario his reaction speed should be "significantly faster."

John focused his mind on motion. He leaped over a 3 meter-high wall. He punched at concrete targets-shattering them. He threw knives, sinking them up to their hafts into the target dummies. He slid under barbed wire as bullets zinged over head. He stood, and let rounds deflect off the armor. To his amazement, he actually dodged one or two of the rounds.

Halo: Fall of Reach
pg. 117 paperback

It doesn't go into much detail on what parts of his armor are bullet proof or what kind of gun/bullet was being used. It is impressive, however, that he actually dodged a couple in his first test run of the suit, considering an hour earlier when he first had it put on he could barely walk in it.

“Good. Let’s go over this one more time.” The Master Chief overlaid a topographic map on their
helmets’ displays.
...
The Master Chief opened the squadwide COM channel. “They’re seventy meters from this depression
—” He keyed a NAV point into the team’s topographic display.

One of the features of his helmet.

The room contained display cases of mineral specimens. There were sulfur crystals, raw emeralds, and rubies. There was a monolith of unpolished pink quartz in the center of the room, three meters wide and six tall. Off to one side, however, were two creatures.

Halo: Fall of Reach (ebook)
pg. 190

The floor creaked, buckled, and then fell away; the two massive aliens plunged into the basement below.
“Quick,” the Master Chief said. He slung his rifle and moved to the back of the quartz monolith.
“Push!”
Kelly and Fred leaned their weight against the stone and grunted with effort. The slab moved a tiny bit. James sprinted forward, slammed into the stone, put his shoulder alongside theirs . . . and pushed. His left arm had been burned away from the elbow down, but he didn’t even whimper.
The monolith moved; it inched toward the hole . . . then tilted and went over. It landed with a dull thud and a crunching noise.

Halo: Fall of Reach (ebook)
pg. 193

Going by the description the quartz had a volume of 54 cubic meters (3x3x6). A cubic meter of quartz weighs 2,650 kilograms. The whole monolith weighed 141,750 kilograms, or 156 short tons. While Chief did have help from 3 fellow Spartans, 1 of which was badly wounded, he still provided at about 1/4 of the force needed to push the Monolith.

He threw his arm around James and helped him along. They ran into the basement, making sure to give the pinned giants under the stone a wide berth, then jumped through the storm drain and into the sewers. They jogged thought the muck and didn’t stop until they had cleared the drain system and emerged in the rice paddies on the edge of Côte d’Azur. Fred rigged the ground-return relay to the pipes overhead and ran a crude antenna outside. The Master Chief looked back at the city. Banshee fliers circled through the skyscrapers. Spotlights from the hovering Covenant transport ships bathed the streets in blue illumination. The Grunts were going crazy; their barks and screams rose to an impenetrable din.The Spartans moved toward the coast and followed the tree line south. James collapsed twice along the way and then finally slipped into unconsciousness. The Master Chief slung him over him shoulder and carried him. They paused and hid when they heard a patrol of a dozen Grunts. The aliens ran past them—they either didn’t see the Spartans, or they didn’t care. The animals sprinted as fast as they could back to the city. When they were a click away from the rendezvous point, the Master Chief opened the COM link. “Green Team Leader, we’re on your perimeter, and coming in. Signaling with blue smoke.” “Ready and waiting for you, sir,”Linda replied.“Welcome back.” The Master Chief set off one of his smoke grenades and they marched into the clearing.

Chief has no trouble carrying a fellow half ton Spartan for at least 1 kilometer, most likely more, from the city of Cote D'Azur to the coastline.

Chief in MJOLNIR Mark V Power Armor feats

Overview
Adds Energy Shield to armor
Strength increased x2
Top sprint speed over 105 kph
Smart A.I.

The Master Chief blurred into motion. He dove from the activation platform and—before the soldiers could adjust their aim—landed in their midst. He rolled to his feet right next to the soldier who fired first, and grabbed the man’s rifle. John brutally yanked the weapon away from the soldier. There was a loud cracking sound as the man’s shoulder dislocated. The wounded trooper stumbled forward, off balance. John spun the rifle and slammed the butt of the weapon into the soldier’s side. The man exhaled explosively as his ribs cracked. He grunted, and fell unceremoniously to the floor, unconscious. John spun to face the left-flank gunner, assault rifle leveled at the man’s head instantly. He had the man in his sights, but he still had time—the soldier was not quite in position. To John’s enhanced senses, amped up by Cortana and the neural interface, the rifleman seemed to be moving in slow motion. Too slow. The Master Chief lashed out with the rifle butt again. The trooper’s head snapped back from the sudden, powerful blow. He flipped head over tail and slammed into the ground. John sized the man’s condition up with a practiced eye: shock, concussion, fractured vertebrae. Gunner number two was out of the fight.
The remaining gunner completed his turn and opened fire. A three-round burst ricocheted off the MJOLNIR armor’s energy shield. The shield’s recharge bar flickered a hairbreadth. Before the soldier could react, the Master Chief sidestepped and slammed his own rifle down—hard. The trooper screamed as his leg gave out. A jagged spoke of bone burst through the wounded man’s fatigues. The Master chief finished him with a rifle butt to his helmeted head. John checked the condition of the rifle, and—satisfied that it was in working order—began to pull ammo clips from the fallen soldiers’ belt pouches. The lead soldier also carried a razor-edged combat knife; John grabbed it. “You could have killed them,” Cortana said. “Why didn’t you?” “My orders gave me permission to ‘neutralize’ threats,” he replied. “They aren’t threats anymore.” “Semantics,” Cortana replied. She sounded amused. “I can’t argue with the results, though—” She broke off, suddenly. “New targets. Seven contacts on the motion tracker,” Cortana reported. “We’re
surrounded.” Seven more soldiers. The Master Chief could open fire now and kill them all. Under any other circumstances, he would have removed such threats. But their MA5Bs were no immediate danger to
him . . . and the UNSC could use every soldier to fight the Covenant. He strode to the center pole of the tent, and with a yank, he pulled it free. As the roof fluttered down, he slashed a slit in the tent fabric and shoved through. He faced three Marines; they fired—the Master Chief deftly jumped to one side. He sprang toward them and lashed out with the steel pole, swiped out their legs. He heard bones crack—followed by screams of pain. The Master Chief turned as the tent finished collapsing. The remaining four men could see him now. One reached for a grenade on his belt. The other three tracked him with their assault rifles. The Master Chief threw the pole like a javelin at the man with the grenade. It impacted in his sternum and he fell with a whoopf. The grenade, minus the pin, however, dropped to the ground. The Master Chief moved and kicked the grenade. It arced over the parking lot and detonated in a cloud of smoke and shrapnel. The three remaining Marines opened fire—spraying bullets in a full-auto fusillade. Bullets pinged off the Master Chief’s shield. The shield status indicator blinked and dropped with each bullet impact—the sustained weapons fire was draining the shield precipitously. John tucked and rolled, narrowly avoiding an incoming burst of automatic-weapons fire, then sprang at the nearest Marine. John launched an openhanded strike at the man’s chest. The Marine’s ribs caved in and he dropped without a sound, blood flowing from his mouth. John spun, brought his rifle up, and fired twice. The second soldier screamed and dropped his rifle as the bullets tore through each knee. John kicked the discarded rifle, bending the barrel and rendering the weapon useless. The last man stood frozen in place. The Master Chief didn’t give the man time to recover; he grabbed his rifle, ripped off his bandolier of grenades, then punched his helmet. The Marine dropped. “Mission time plus twenty-two seconds,” Cortana remarked. “Although, technically, you started to move forty milliseconds before you were ordered to.”

Fall of Reach (ebook)
Pg. 232-234

Defeats 3 ODSTs and 7 Marines in 22 seconds while starting unarmed and goes out of his way to ensure he doesn't kill any of them.

That aside, I want to focus on the part where a burst from an assault rifle does a bit of damage to his shields. If we take the hairbreadth literally, it means the shield recharge bar was brought down 100 microns or 1/10mm. Next, how long is the energy shield bar? Using an image of the Halo CEA shield bar and Halo CEA helmet, I figure the visor is around to 300mm (1 foot) wide when stretched out, on the inside HUD the shield recharge bar is rather small, approximately 1/8 the length of the  visor. That’s about 37.5mm for the shield bar. One 3 round burst from the MA5B rifle brought it down by 1/10mm, so it would take 375 bursts to take it down fully, or about 1125 bullets. The 7.62x51mm FMJ fired by a MA5C has a muzzle velocity of 905 m/s and weighs 10 grams.

KE= 1/2(M*(V*V))
0.01*905*905=8190
0.5*8190=4095

So 4 kilojoules per round. That means it takes 4.6 megajoules to take down the energy shield of a Mark V, again, assuming we take hairbreadth literally.

“Wait,” Cortana said. “I’m picking up far infrared signals on your thermal sensors. An encrypted sequence . . . decoding . . . yes, there. It’s an activation signal for a Lotus mine. They’ve mined the field, Master Chief.”

Suit's sensors pick up anti-tank mines.

Along either side of the course there was something new: three 30mm chain-guns mounted on tripods.
...
Two more grenades and the automated guns were out of commission. He noted that his shields had dropped by a quarter. He watched the status bar refill. He hadn’t even known he had taken hits. That was sloppy.

Halo: Fall of Reach (ebook)
pg. 235-236

A modern day 30x173mm fired from a M44 Bushmaster II chaingun has around 220 KJ. Multiple hits (at least 2) would be 440 KJ to drop his shields down a quarter and 1.7 MJ to drop it fully. This is somewhat low end since I'm assuming only two rounds hit.

It was a forest of ten-meter-tall poles spaced at random intervals. Typically, the poles had booby traps strung on, under, and between them—stun grades, sharpened sticks . . . anything the instructors could dream up. The idea was to teach recruits to move slowly and keep their eyes open. The Master Chief had no time to search for the traps. He climbed up the first pole and balanced on top. He leaped to the next pole, teetered, regained his balance—then jumped to the next. His reflexes had to be perfect; he was landing a half ton of man and armor on a wooden pole ten centimeters in diameter.

Halo: Fall of Reach (ebook)
pg. 237

Decent agility feat.

“Motion tracking is picking up an incoming target at extreme range,” Cortana warned. “Velocity profile matches the SkyHawk, Chief.”He turned—almost lost his balance and had to shift back and forth to keep from falling. There was a dot on the horizon, and the faint rumble of thunder. In the blink of an eye, the dot had wings and the Master Chief’s thermal sensors picked up a plume of jetwash. In seconds, the SkyHawk closed—then opened fire with its 50mm cannons. He jumped. The wooden poles splintered into pulp. They were mowed down like so many blades of grass. The Master Chief rolled, ducked, and flattened himself on the earth. He caught a smattering of rounds and his shield bar drooped to half. Those rounds would have penetrated his old suit instantly.

Halo: Fall of Reach (ebook)
pg. 238

Motion tracker picks up a fighter jet on the horizon. Since he's standing on a 10 meter tall pole the distance to the horizon is 11.3 kilometers, if it were on Earth. However, Reach is actually bigger than Earth (15,273 km in diameter compared to Earth's 12,742 km) so the distance should be a bit more. That's pretty crazy range his MT has, for aircraft anyway.

Calculator used to measure distance of the horizon.

Takes "a smattering of rounds" to drop his shield to 50%. Since smattering isn't an exact value I'm going to assume he took 1 hit from each gun (the SkyHawk has 4). No surprise there isn't much info on the 50mm cannons used by the UNSC so I'll use stats from a WWII German 50mm gun, the KwK 39.

Projectile weight - 2.06 kg
Muzzle velocity - 835 m/s

2.06*835*835=1436283
1436283*0.5=718141.

718 KJ per shot, 4 shots = 2.8 MJ, 5.6 MJ to fully break his shields.

The Master Chief got up and ran through the shattered remains of the poles. Napalm and sonic grenades popped around him, but he moved so fast he left the worst of the damage in his wake.

Halo: Fall of Reach (ebook)
pg. 238

Doesn't seem bothered by napalm or sonic grenades even though his shield is at half strength.

“I’ll need your help, Cortana,” he said. “Anything,” she whispered. The Master Chief heard nervousness in the AI’s voice. “Calculate the inbound velocity of a Scorpion missile. Factor in my reaction time and the jet’s inbound speed and distance at launch, and tell me the instant I need to move to sidestep and deflect it with my left arm.”
Cortana paused a heartbeat. “Calculation done. You did say ‘deflect’?” “Scorpion missiles have motion-tracking sensors and proximity detonators. I can’t outrun it. And it
won’t miss. That leaves us very few options.” The SkyHawk dove.
“Get ready,” Cortana said. “I hope you know what you’re doing.” “Me, too.” Smoke appeared from the jet’s left wingtip and fire and exhaust erupted as a missile streaked toward him. The Master Chief saw the missile’s track back and forth, zeroing in on his coordinates. A shrill tone in his helmet warbled—the missile had a guidance lock on him. He chinned a control and the sound died out. The missile was fast. Faster than he was ten times over. “Now!” Cortana said. They moved together. He shifted his muscles and the MJOLNIR—augmented by his link to Cortana— moved faster than he’d ever moved before. His leg tensed and pushed him aside; his left arm came up and crossed his chest. The head of the missile was the only thing he saw. The air grew still and thickened. He continued to move his hand, palm open in a slapping motion—as fast as he could will his flesh to accelerate. The tip of the Scorpion missile passed a centimeter from his head. He reached out—fingertips brushed the metal casing——and slapped it aside.
The SkyHawk jet screamed over his head. The Scorpion missile detonated. Pressure slammed though his body. The Master Chief flew six meters, spinning end over end, and
landed flat on his back. He blinked, and saw nothing but blackness. Was he dead? Had he lost? The shield status bar in his heads-up display pulsed weakly. It was completely drained—then it blinked red and slowly started to refill. Blood was spattered across the inside of his helmet and he tasted copper.

Halo: Fall of Reach (ebook)
pg. 239-240

Proximity blast from ASM hits him, takes out his shields and sends him flying 6 meters.

He stood, his muscles screaming in protest.
“Run!” Cortana said. “Before they come back for a look.” The Master Chief got up and ran. As he passed the spot where he had stood to face down the missile, he saw a two-meter-deep crater. He could feel his Achilles tendon tear, but he didn’t slow. He crossed the half-kilometer stretch in seventeen seconds flat and skidded to halt.

Halo: Fall of Reach (ebook)
pg. 240

That's 29 m/s or 105 kph (65 mph)

"Overpressurize your hydrostatics just before you hit." That would risk nitrogen embolisms for his Spartans, but they were coming in at terminal velocity, which for a fully loaded
Spartan was—he quickly calculated—130 meters per second. They had to overpressurize the cushioning gel or their organs would be crushed against the impervious MJOLNIR armor when they hit.

Halo: First Strike (ebook)
pg. 17

Even though this is technically a feat for Fred, he was wearing the same Mark V as the Master Chief

so it's usable.

451*130*130=7621900
7621900*0.5=3810950

The impact would have been 3.8 MJ, though they did hit the trees on the way down, slowing them down

a bit, so it may have been less.



Chief in MARK VI power armor feats

Overview
Increases strength x5
Faster and stronger energy shields
Built-in biofoam heals injuries




Increases strength by a factor of 5, putting his lifting capacity at about 4300 kilograms, or 2.15 short tons. Assuming no growth in strength or body weight since his early teenage years, which is would be ridiculous, but this is a low end. If we go with Frank O'Conner's comment on Spartans being 400 pounds though, then Chief should be able to lift at least 5,985 pounds or about 3 short tons (still assuming to growth in strength since early teenage years).




This one's more of a badass moment, riding a ghost on a huge ass explosion.






Survives an explosion that turns the Brute Chieftian and grunts around him into ash, unshielded.

The concrete beneath the Spartan had turned to dust and gravel as he launched forward. Barely half a second had passed and he was already ten meters away. Palmer slung her weapon and tore off after him; Sullivan fell in directly behind her, running for all he was worth.
Palmer was pumping her arms and trying to control her breath as she trailed behind the Spartan. She looked up from her boots and saw that his hands were no longer empty—his right hand now held a massive hard-chromed M6D, and a spare magazine was in his left. Eight thunderclaps rang out so fast that they bled together into a single long roar. At that same moment a terrible cacophony erupted behind them as her squadmates opened fire on the building—its facade disappearing behind a cloud of pulverized concrete and shattered glass. Two of the Jackals that had been covering their approach had already fallen—bright purple blood fountaining out of huge ragged holes that she could pick out even at this distance.
With one hand at thirty meters and a dead run, two shots apiece, each a hit to the head or neck, what the holy hell are my guys even aiming at back there—shit.

Ik it's been 3 years but if you're still active please finish this. Mjolnir mark 6 worn by Fred took a direct hit from a Hunters assault cannon and although it brought down his shields, made his armor red hot and kod him for a few moments, the armor itself held and recharged moments later with Fred himself readu to fight. All of that at most took a few moments.
