I just did the Jack of all trades achievement twice...and no credits for it....I got a kill with::::HandGrenade / Submg(thomp or mp40) / MG (mounted ones) / Rifle (kar/gar) / Sniper....any notations im missing?
I'm currently working on Jack of All Trades......Seriously tough...I've been down to the last kill (usually gatta go find a sniper) several times, but no dice so far
