Fecespult

A large cart loaded with the waste of their civilization, the Moblins adopted the barbaric but effective tactic of launching such filth at enemy armies. While not likely to injure or kill enemy soldiers, the sudden rain of excrement and lingering smell can easily break the morale of most soldiers.

Name: Fecespult or Dungpult?
Officially the unit is call Fecespult but UndyingNephalim said "I might call it the Dungpult instead, it sounds nice and crude."
