When a man is lying in a shell hole, if he just stays there all day, a German will get to him eventually. The hell with that idea. The hell with taking it. My men don't dig foxholes. I don't want them to.
Foxholes only slow up an offensive.
And don't give the enemy time to dig one either. War is a bloody, killing business. You've got to spill their blood, or they will spill yours. Rip them up the belly. Shoot them in the guts.
