In 15mm, some of the old glory american paras are so armed. …
Some of their regular GIs are also so armed, and I think they're fine figures*
They may be fine figures … I don't pretend to be an experienced judge of 15mm stuff. But looking at the pics, I will say that I don't see ANY figures carrying an M3 grease gun.
In the top pic I clearly a soldier on the left carrying a Thompson (Tommy gun, if you prefer), and a soldier on the right carrying what might be interpreted as an M1 carbine (or maybe something else…), and one soldier in the center carrying what appears to be an odd form of a sawed-off or shortened Tommy gun. But there is certainly no one carrying anything that resembles a grease gun.
In the bottom pic I clearly see a soldier on the right carrying a Tommy gun, and soldier in the center with an M1 rifle ("Garand"), and a soldier on the left again carrying something I can not readily identify. Looks almost like a French MAT-49 … I know that doesn't make sense, and it doesn't look like a particularly well modeled MAT-49, but that's about the closest I can get with what we see.
The simplest and most clear visual identification characteristic of the M3 grease gun is the barrel. It has no shroud, no forestock, no foresight, no muzzle brake, no flash suppressor, nothing. It is nothing but a round tube protruding from the receiver assembly. It is fairly distinctive in this regard. There are many SMGs with folding stocks and long vertical box magazines, but I can't think of another that has such a distinctive barrel.
I just don't see any grease guns in those pics…
