You're right! It didn't occur to me at first when Arnold spoke about the severely wounded soldier "and the list goes on and on" concerning his wounds. But the fighting ethics of today's soldier tell them to return to the unit and fellow soldiers. Not to use war wounds to get out of fighting.
It wasn't my observation, it was CIB-173RDABN who made it. The media will ignore it completely, even if a pundit figures it out.
