I don't have a lot of completed work posted anywhere... That's because I have so few works that are complete, lol.. You're correct though, I only do dioramas... Most of my suff is in the diorama forum, although I've got a few WIPs in the Armor and Aircraft forums...
As you surmised, I did indeed retire from the US Army after 30 years, beginning at age 17 in 1976. I spent my career in various units; Artillery, Infantry, Engineer, Aviation, and a stint in USAREC as a Recruiter and another in as an Instructor at the US Army Chemical School in Ft McClellan, AL.
