I just think its a bad look. I know it was all volunteer but they should have told him no. Perhaps he did serve just as well if not better than someone who wasn't an amputee - kinda like Oscar Pistorius being in the Olympics, but again the optics of it don't make sense for me.
You know what he should have done was been a recruiter. He might have been able to guilt trip some of these evaders into joining.
