Also the first game's ending, where you launch the sabotaged V2 rocket. The scientists' responses are priceless. Below is a translation to what the scientists say...
...abort the start! I repeat! Abort start!
Control room here, all of our control panels are broken. The start of the rocket can only be aborted at the starting ramp. Hurry!
Abort start! ABORT! Abort ignition!
10, 9, 8, 7, 6, 5, 4, 3, 2, 1!
Abort! Abort start!
Everyone get out of the building!
RUN FOR YOUR LIVES!
We're going to die!
It's coming down on us—
(After the explosion)
The American... has won...
Pacific Assault has this little bit with Frank and Willy, after Frank gets promoted to Gunnery Sergeant:
Frank: Stripes come from up high, you redneck.
Willy: Oh, I know where they come from. I'm just making sure you're not pulling our legs is all. You know... Like when you talk about how the ladies love ya.
Frank: Oh, you're a cocky little son of a bitch! I've put up with your crap since boot camp!
*Equipment is unloaded, making a lot of noise*
Frank: You're gonna get it, Willy!
Willy: I guess we'll talk later then! Okay, buddy!
