After the napalm attack :

KILGORE
"You smell that? Do you smell that? Napalm, son. Nothing
else in the world smells like that. I love the smell of napalm
in the morning. You know, one time we had a hill bombed, for
twelve hours. When it was all over I walked up. We didn't
find one of 'em, not one stinkin' dink body. The smell, you know
that gasoline smell, the whole hill. Smelled like - victory.

Someday this war is gonna end."
