Aeria did some art of Vietnam War era Tros, and I couldn't wait to show it off!
Tros enlisted, though not enthusiastically, when he was in his early 20s. He did one tour and was done with it, but he did indeed see quite a bit of combat in that time. Despite that, he always had an attitude about him that he'd be fine, perhaps from some sort of bull-headed arrogance or sheer delusion, but it served him well, seeing as he not only lived through the war but came home still well put-together.
