I had the same thought in ROTC. My 2nd or 3rd FTX we got to dig our first fox hole. Actually just, just a scrape (I forget the military term, but there was one) to hide behind, about two feet deep,body length, with the dirt in front as a berm. Luckilly for us, it was in the loamy soil of Va. However, we had been up since 5am run, marched, etc. However it was AFTER our first day on the grenade range tossing live ones. No one asked why we were doing this.
