My son is a combat medic. He absolutely hates helicopters. He doesn't really like planes, but he hates helicopters. When he was injured he was laughing and joking until they loaded him on a helicopter and then he started trying to get up and walk. Was apparently insistent that he'd rather walk. I think they knocked him out at that point.
Medics are my favorite kind of soldiers. God bless you, your son and your family. It's tough to be a soldier and a military family in the best of circumstances and, of course, more so during wartime. Your sacrifices are deeply appreciated.
Best,
