what are some things the men say they will do if it was peacetime?

Haie would get himself a woman.

"By Jove, yes," says Haie, his face melting, "then I'd grab some good buxom dame, some real kitchen wench with plenty to get hold of, you know, and jump straight into bed. Just you think, boys, a real feather bed with a spring mattress; I wouldn't put trousers on again for a week."

Albert says he'd get drunk.

Kat agrees with the drinking but adds the train for home....

"You might get drunk first, of course, but then you'd take the next train for home and mother. Peace-time, man, Albert--"
