I picked up a few dogs too. I like dogs. Both little plastic ones and real ones.
These life jackets I always used as bullet proof vests. Life jackets were not too useful for most land combat operations.
The helmets were great too. The nice things about the separate items was the ability to take the same pose and make him into several different figures. I tried to have at least two pieces on each figure, but it was hard to find that many bits.
