Murdoc uncovered a story which mentions that the US Army still has the WWII era M3 “grease gun” submachine gun in service for select units such as vehicle crews, engineers and radio operators.

Interesting if true.

There is a discussion about it here.

    I know this is dated, but the Army had a lot of them stored in Panama in the late 80s and early 90s; although they were considered "obsolete."

    I was a 63Y (track vehicle mechanic) during the first gulf war in 1991. I drove an M578 ( a tracked vehicle used to recover other tracked vehicles from the battle field - a combat tow truck if you will). Anyway, me and my sergeant were both issued Grease Guns (and M1911 .45 pistols). We had tons of ammo for the grease guns, so we spent a lot of time shooting them in the Saudi desert. Although very old, they are rather nasty weapons at close range. We also were issued M16s, a mounted .50 cal machine gun, and two AT4 anti-tank rockets. I remember at the time being impressed with how heavily armed we were as mere mechanics.
