I had a whole bunch of GI Joe stuff when I was young, but my mother didn't like the "war" style GI Joes... Anybody else remember the accessory kit that included the crutches and bloody bandages? lol. She REALLY hated that one, and refused to allow me to get it! But I did have the deep sea diver, complete with octopus, and the space ship!

My older brother had a toy soldier set that included cannons that could shoot (spring loaded, not caps). We thought it was great fun to use the stop signs as shells, as they fit the cannons perfectly.
My favorite was the tank, mostly because it was battery-operated.
But the thing was a technological marvel of the toy world for the age bracket- the barrel direction could independently control the power transmission to the tracks, allowing the tank to actually turn like real tanks do.
