German Sausage Drop
During WW2 it's common knowledge that solders would drop grenades in the man hole or hatch of a tank to kill the solders inside, however the german sausage drop is a lesser known tactic. The german sausage drop is when a solder takes a shit or throws shit into the hatch of a german tank in an attempt to literally gas them out.
My grampa ran out of grenades in world war 2 so he used the german sausage drop strategy .
