Disabled vets are allowed a max percentage of disability (30% I think). I worked with 2, and one had a 10% disability, that was from running too much, as a Ranger. I don't know about anyone else, but I'm o.k. with that. The other broke an ankle from a parachute drop (Airborne Ranger), also around 10%. I think I'm o.k. with that as well. I do not think anyone needs to argue that if one has a "Purple Heart", with limited disability, should be o.k. As for "physically demanding", in 5+ years, I had to run once, and wrestle once. In the overall scheme of things, not very demanding. If the disabled vets were in my position, they could have handled both situations just as well.
