Yes and I prefer the term "weapons" (then again, aw never mind). It also might depend on your definition of a "dummy".
Have you ever had your Drill Sergeant (for us Army types) discipline you by making you spend a hot summer day cleaning with a toothbrush and a cup of water? Oh it was a dumpster and I had to clean and from the inside. I think I can still smell it (wheeew).
Yes, to both those situations.
Ever had a live grenade drop into one of said foxholes and thanking God you remembered how to correctly dig a grenade sump and wishing you could jump a bit higher?
No, luckily it happened three positions over during basic at the grenade range... baseball should be a required course of instruction in high school by God.
Have you ever watched a war movie and not uttered the phrase, "That ain't right."?
