POWs get "taken care of" by our services. If the member is able to and wishes to continue serving, they are allowed to. Glenn retired after 30 something years as a Chief Master Sergeant. He was part of the Berlin Air Lift, served during Korea and into Vietnam, but I can't tell you what jobs he held. My 13 years older Aggie cousin said but you wanted to be careful around Glenn for both his safety and yours.
