I joined the Army out of high school with a buddy. After basic training I tried to get him to go to medic school with me, but he said "no way, I want a safe job in the rear with the gear". So he became a truck driver.
I ran into him about 9 months in country at a field hospital. His job consisted of driving a dump truck full of dirt, backwards in front of tank convoys, looking for mines. A dump truck & a private, were much easier to replace than a tank. He was recovering from hitting a mine & had earned his second Purple Heart!
There aren't many safe jobs in the Army
