A squadron of U.S. Marines becomes the last line of defense against a global invasion.

SSgt. Michael Nantz: All right, Lockett. You wanna go there. Let's go there. I commanded men and men died. Kids. 19 years old. The best men I ever led. Do you think for a second I wouldn't rather trade places with them? I know you think I got my men killed. They're dead. I'm here. Like the punchline to some bad joke. You think I like that? Do you think a minute goes by that those faces aren't right here
[points to head]
SSgt. Michael Nantz: seared into my brain?

Sgt. Major: At 14:46 Pacific Standard Time, 12 different locations around the world were breached, in what appears to be a coordinated attack by an unknown enemy. All breaches were along the coastline, in what is a campaign of rapid dominance. This is a textbook military invasion. There are massive casualties in New York, defensive lines are being setup in Boston, and at 13:15 Zulu Time we lost communications with San Francisco and San Diego, their status is unknown. What we do know is that we are the LAST offensive force on the west coast, we can NOT lose Los Angeles.
Michele: Maybe I can help. I'm a vetinarian.
[She mispronounces veterinarian]
1st Sgt. John Roy: [trying to talk him out of his retirement decision] You know, we could always use another lean mean typing machine.
SSgt. Michael Nantz: Shit, I ain't built like you John. Ugly, slow, soft.
Cpl. Lee Imlay: [looking at map] This map shows where all the units were deployed... what do all these red marks mean?

Reporter on TV: ...an unprecedented meteor shower falling off the coast of Tokyo. The entire city is mesmerized by this incredible sight. Two hours after the first contact, an unidentified enemy has reached our coastlines in a swift and militaristic attack. Right now one thing is clear: The world is at war.
Lt. Col. K.N. Ritchie: We have an infestation of God-knows-what in there but they are NOT from this Earth and we gotta hit them with everything we got! They are a ground force enemy only, so the Air Force will tear them a new asshole and we *will* rule the air! Now you got 3 hours to get your ass back before those bombs drop, and make no mistake THEY WILL DROP! with... or without you.
2nd Lt. William Martinez: Get them out!

Cpl. Lee Imlay: You mean like from space?
Cpl. Nick Stavrou: No Imlay, from Canada.
SSgt. Michael Nantz: ...but none of that matters right now.
SSgt. Michael Nantz: U.S. Marines! How many?
Michele: Five of us! Three kids!
LCpl. Steven Mottola: It's a no-go on the helo sir. Their air support is lighting it up. Command says it's like nothing they ever seen before.

Michele: [discussing the silence after bombing run deadline passes] Could they have taken out the whole Air Force?
TSgt. Elena Santos: [shocked] This isn't happening...
Cpl. Kevin Harris: You saw that?
TSgt. Elena Santos: [laughs] They're going down like bowling pins!

SSgt. Michael Nantz: I thought you were a doctor.
Michele: [smiles] Animals and aliens only.
2nd Lt. William Martinez: [about Nantz's heroics] That was some new John Wayne shit, Staff Sgt.
