Yep!  Did the plastic army men with bb guns too.  A good hit made a little dimple in the plastic.  But ten pumps with a pellet rifle and they broke in half.  Those army men toys I had were all Vietnam era, carrying M16s.  I was more into WWII even then and usually played with 1/72 scale WWII figures.  My dad found them somewhere for me.  There were Germans and Americans.  And had some Minitanks HO scale vehicles too.

I bought a plastic armyman - tank toy a few years ago for nostalgia.  It's on my shelf.
