Irie answered my question with 100% accuracy.

Picture this...Your fighting in a trench and the guy beside you gets capped. During a break in the fighting you burry him in the wall of the trench you are in, front or back side which ever still has space. A lucky bomb blows the trench open a month later.....you get the picture. Not to mention the fleas, rats and constant mud.
