Lol. Boomerang is funning with you, using Catch 22.
It is an absolutely classic satire upon the horror and futility of war - and the military machine.
Heller sets it in WW II, but was, himself, in the Korean war, as I understand it.
It is an extremely black, but very humanist, and humane, satire.
I find the sexism pretty revolting - but still enjoy it for its brilliance and stunningly iconoclastic vision.
It is also extremely funny.
