A true career soldier Oz had been passed over for every promotion for his entire time as a soldier, never rising above the enlisted ranks. He was under Stacey's command during the mission that earned Stacey his demotion. He knows nothing was Stacey's fault and that's why he offered the information about the Abysmian treasure. He also figured his share would make for a nice retirement nest egg. Too bad he'll never enjoy any time off now that he is working for The Dreadnoks.
The head got a lot of work on it. Years ago I had removed the hat and sculpted a bald head with Sculpey. Never finding a use for it, I added the horseshoe hair and muttonchops out of green stuff for this project. I wanted this guy to be lifetime vet looking for a quick buck.
