If the enemy is around and ya need to take a dump that badly ... well ... eff the hole. Find as safe a place as possible ... NOT yer fox hole ... git 'er done ... and let it lie where it is. Hopefully, if the enemy is tryin' to infiltrate, they'll step on it, slip, and fall on their ass with a crash.
The essential American soul is hard, isolate, stoic, and a killer. It has never yet melted. ~ D.H. Lawrence
