Yes, Cleland was crippled as the result of an accident, not as a result of combat. However, Cleland did win a Silver Star for valor in combat a short time before the accident which ended his tour. A Silver Star is a serious combat medal, not the sort of thing they just hand out to anybody.
Coulter said that Cleland was ‘no hero’, and I think that’s what got her into trouble. I’m no fan of either Coulter nor Cleland, but Cleland has earned my respect for his service. He’s a victim, and a hero, one right after the other.
