Quote context

[...]

- Yes, sir. (2)

- Major Kong, is it possible this is some kind of loyalty test? You know, give the go code and then recall to see who would actually go?

- Ain't nobody ever got the go code yet.

- Old Ripper wouldn't be giving us Plan R unless them Ruskies had already clobbered Washington and a lot of other towns with a sneak attack.

- Yes, sir. (3)

- Major Kong, message from base confirmed.

- Well, boys, I reckon this is it. Nuclear combat toe-to-toe with the Ruskies.

- Look, boys, I ain't much of a hand at making speeches. But I got a pretty fair idea that something doggone important is going on back there.

- And I've got a fair idea of the kind of personal emotions that some of you fellows maybe thinking.

- Heck, I reckon you wouldn't be human beings if you didn't have pretty strong personal feelings about nuclear combat.
