The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed or transferred. When vents are blocked in a system, heat cannot escape, causing pressure to build up until the system fails. This principle was demonstrated when a mechanic accidentally caused a radiator explosion by pouring Stop Leak into the engine, blocking the vents and trapping heat. The same principle was later applied to destroy an alien machine by blocking its vents with rocks, causing pressure buildup and explosion.

They Called Jack Reacher Mentally Unfit—His Combat Skills Proved Them Wrong.Added:
Good copy, Sabre Patrol. You're exiting the green zone now. 10th Mountain's convoy is stranded, no sitrep. Be advised, Barton's convoy's in a black spot. Comms will be sketchy, stay sharp, watch your six.
Who's the full-fledged [ __ ] responsible for this [ __ ] Who's the meathead calling me a [ __ ] Meathead.
You [ __ ] up my morning pass. Oh, but what are you going to do about it? I'm going to do about what?
Wake up, [ __ ] Welcome to the final week. Rangers are the spearhead of the United States Army. We are first on the ground every single time.
The fate of our nation and allies depends on our expertise. DO YOU UNDERSTAND ME? YES, FIRST SERGEANT.
YOU ARE about to embark on eight weeks of the hardest selection program in the world.
Whether you have been deployed in combat or you are fresh out of basic, you can expect [music] your emotional, physical, and mental strength to be pushed to the absolute limit and then some. You are wrong.
The movie begins in Afghanistan with a Staff Sergeant 81 heads out to repair a stranded convoy. When the combat engineer steps out of the vehicle, he angrily asks which idiot caused the problem that ruined his day. The squad leader steps forward and admits responsibility. It quickly becomes clear that the two men are actually brothers.
Who's the full-fledged [ __ ] responsible for this [ __ ] Meathead calling me a [ __ ] Meathead.
You [ __ ] up my morning pass. Oh, but what are you going to do about it? I'm going to do about what?
NOOKY, BABY. WAIT, you know this guy?
This what?
This my big brother and I'm nuts.
Good to see you, bro.
Too. The older brother then explains the problem using the laws of thermodynamics. Energy cannot be created or so it must go somewhere. By filling the trucks with Stop Leak, the vents became blocked, trapping heat until the radiator eventually exploded. He jokingly tells his brother that he should have known it was his idea to pour Stop Leak into the engine. The younger brother sighs and admits that this is not the life he wants.
He reminds his brother of their shared dream, earning a place in the Army Rangers through Rasp. He even points to the matching tattoos they both got that read >> same tattoo by coincidence.
First law of thermodynamics, energy can't be created or destroyed, so it's got to go somewhere.
Block the vents, heat can't escape, pressure builds till the radiator blows.
It was you.
Mechanics keep writing you out.
Just as the conversation begins to change his mind, Taliban fighters suddenly ambush the convoy. A brutal firefight breaks out, killing nearly everyone. With a badly injured knee, the older brother drags himself toward his wounded sibling.
>> Yes, Army Rangers. Starting to regret saying yes already. Tier one, baby.
Two years later, he rides a bus toward the Army Ranger selection program in Colorado.
Upon arrival, the cadre instruct the candidates to report to the induction hall and surrender all personal belongings. From that moment on, they will no longer use their names, only numbers.
5 minutes to base. Get your packs ready.
Candidates, proceed at pace TO THE INDUCTION HALL IMMEDIATELY. PLACE YOUR NAME TAPE IN your right inside that duffel my You no longer HAVE A NAME. YOU ARE A NUMBER. You are now number 44. The Ranger Assessment and Selection Program.
Each candidate receives a number. His is 81. He's attempted this program four times. This time he barely meets the age limit. As a staff sergeant, he could step in as a team leader, but he refuses. He wants to earn it like everyone else.
Applied four times, medically denied each time. You just made the age cut off. You got a plan B?
No, sergeant.
You will be assigned team leader. State your consent. I'd rather not.
You are now number [music] 81.
Yes, >> The first sergeant addresses the group.
For the next 8 weeks, their bodies and minds will be pushed beyond their limits. Most will quit.
And even those who endure everything must face one final challenge, a brutal 24-hour mission known as the death march. Only those who finish will become Rangers. Rangers are the spearhead of the United States Army. We are first on the ground every single time. The fate of our nation and allies depends on our expertise. DO YOU UNDERSTAND ME? YES, FIRST SERGEANT.
YOU are about to embark on 8 weeks of the hardest selection program in the world.
RANGERS LEAD THE WAY. ALL THE WAY.
WELCOME TO RASP. TRAINING begins and it's as punishing as promised.
Relentless running, live fire drills, hand-to-hand combat, sleep deprivation, exhaustion. Week after week, candidates drop out, but 81 keeps going. He runs faster than most, fights harder than most. Come on, candidate. Let's go, LET'S GO, LET'S GO.
17, LET'S GO.
10, HALF OF IT. LET'S WE ARE looking for elite warriors, the best of the best.
17, get the [ __ ] out of here. Every week, those who fail will be eliminated.
16, 27, 29, 53, step forward.
Pack your bags. You are non-select.
Thinking about quitting? Do it now. In combat drills, he defeats every opponent. Yet, something about him stands out. He keeps to himself, eats alone, sleeps alone, and declines leadership roles every time.
It's clear he's carrying something heavy. Many recognize his story.
Thinking about quitting? DO IT NOW.
RANGERS, LEAD THE WAY.
That's what he said.
Holy [ __ ] That's him. Two years earlier, his squad was ambushed in Afghanistan. He was the soldier who carried his wounded brother Miles through enemy territory. The one who earned a Silver Star. But, he doesn't look proud.
He looks haunted.
What happened to him? 213th was helping a stranded convoy. Taliban showed up and smoked the whole unit.
Holy [ __ ] That's him.
He already got a Silver Star.
What?
One night, another candidate, number seven, spots him quietly taking painkillers. He also notices a tattoo on his arm, DFQ. When he asks what it means, 81 says nothing.
>> Just a physical test.
DFQ.
Don't [ __ ] quit, right?
Lucky guess.
Training continues, but the past keeps breaking through. Loud noises, explosions, combat drills, all trigger memories of that day. Fight! Fight!
Fight!
This [ __ ] will save your life.
During a water exercise, candidates must walk along the bottom of a pool while carrying heavy weights. Halfway through, the memory overwhelms him. He sees himself dragging his brother through the desert, his legs shattered, blood everywhere. He blacks out underwater.
The instructors pull him out just in time.
I got you.
Later, the sergeant major calls him in.
Physically, he's one of the strongest candidates they've seen, but mentally he's struggling. He isolates himself. He barely sleeps.
Records show that the morning he left Afghanistan, he applied to this program, and he's reapplied every year since. The sergeant major advises him to withdraw before the final test, but 81 refuses.
He just needs to finish. The instructors let him continue. You applied for RASP, and in fact, since then, repeatedly applying for RASP seems to be the only thing you've done.
Now, why is that?
Get across a finish line, Sergeant Major. I just want to What I have here is a voluntary quit slip. Sign it.
You're an engineer.
So, you know even the most powerful machines have their limits.
And I think you've reached yours.
Soon, the final mission begins, the death march. Helicopters drop the candidates deep in the jungle.
One down. Goes one up. Shift into cover.
Goes two to TOC command.
>> time, 81 is assigned as team leader, whether he wants it or not. They move out. That night, something streaks across the sky at impossible speed. At first, they assume it's artillery.
Any questions?
What if I have a war?
We're all here for one reason.
We never give up.
Follow me.
By morning, they realize it's something else, a strange aircraft. When it activates, chaos erupts. It scans them, then opens fire. This isn't part of the exercise.
It's a machine, a weapon unlike anything they've seen, and it starts hunting them. Soldiers are killed within seconds. The survivors scatter. Some fall from cliffs, others are swept away by rivers. The machine relentlessly pursues them.
So, it's classified.
Put it down.
I can't get a signal.
Keep your eyes open.
The hell is that?
Retreat!
>> [screaming] [screaming and groaning] >> What?
>> [screaming] >> They eventually reach a nearby village hoping for help, but find it completely destroyed. Every soldier there is dead.
That's when the truth sinks in. The object NASA believed was an asteroid was something else, something alien. And it didn't come alone. One by one the team is wiped out until only 81 and 7 remain.
7 is badly injured so 81 carries him through rain, mud, and steep terrain until he finally collapses.
You sure this is the village?
This was it.
No.
How high have we climbed? About 6,500 ft.
About eight clicks west.
About that.
Here.
Wait.
You mean it's from another planet?
Oh!
It's not about us anymore.
Getting 7 back to base and [music] warning everybody that thing's coming.
Don't have time. 15!
Hey! Stop!
Who the hell are you talking to?
I said Seven speaks quietly. He reveals that he once trained with 81's brother. Then he tells him something important. Carrying his brother like that, even if he didn't make it, wasn't failure.
That's what Rangers do. They never quit.
I was on fire and I already passed.
Why didn't you tell me?
I tried.
I was supposed to stop this thing.
What would your brother do?
It's venting.
I got an idea.
At that moment, the alien machine finds them again. But 81 notices something, steam leaking from its vents, an idea clicks. He lures the machine to a quarry, traps it in a crushing pit, and blocks its vents with rocks, just like the radiator he described years earlier.
Heat builds inside, pressure rises, then it explodes.
>> [groaning] >> Would you wait here for me?
I can wait.
>> Come on.
The next morning, 81 carries 7 all the way back to base. They cross the finish line, they made it. But there's no time to celebrate. The war machines are invading Earth. Thousands of them. Every nation prepares for war. When the sergeant major asks how 81 destroyed one of the machines alone, his answer could save countless lives. Right there, the sergeant major pins the ranger tab onto his uniform and asks him to speak.
81 steps forward and delivers a speech that ignites everyone in the room.
Moments later, the rangers deploy because the real war has just begun.
