Many, if not most “regular military” jobs in Western armed forces don’t involve front line combat and getting shot at or shooting at people. Less than 10%.
Now obviously, you look at Ukraine and think “Well that’s a lot bigger than 10%,” and it probably is. But any country with a large air force, navy, and sizeable ground forces are gonna have thousands of people trained to load weapons onto planes, manage ship engines, cook, drive supply trucks, load cargo planes, cook, manage payroll, manage procurement of equipment, fly drones, cook, run propaganda and recruitment, operate medical facilities… the list goes on.
I had an ex whose brother was going to med school to be a surgeon for the Navy. Her father, who was an Army pilot, thought it was great because he knew his son was just gonna be (relatively) safe on a carrier or hospital ship somewhere, not getting shot at, and just saving lives.
