Talk:M79 Grenade Launcher
Wombat Gun? Slime - whatever some Yank gunnutsite might tell you, I have never heard any Australian soldier refer to the M79 by this name. Most Diggers, when asked, scratch their heads in bewilderment at the term.
An update on that last comment: One Oz infanteer remembered the term "Whoompah" used in one unit. The Yanks might've misheard. (Most Seppos wouldn't know what a wombat is anyway - probably think it's an Aboriginal war-club or something.)
