a common military anti boredom
tool. produced when you take the mre heater and drop it into a half full, plastic canteen. as the canteen is air tight for chemical warfare purposes, the pressure
will build until it explodes. not very devistating, but a very
nice pop in the middle of the night!
"Why is Spc
Dingleberry emptying all of those latrines?"
"yeah, he rolled an canteen grenade into Sgt tinydicks tent last
night after he caught him having cyber
sex with his wife."
"Damn."
