Anecdotal, but my mother was a mechanic, my uncle a cryptographer, another uncle was some type of police on base, my cousin is a drone pilot and just sits in an office like building despite technically being involved in combat I suppose. Several former colleagues mostly did admin-type work while enlisted. The last person I know to have actually seen combat was my grandfather in Korea--but he knew what he signed up for and it was fairly deliberate at the time, he had wanted to be like his cousin that had fought on Iwo Jima years prior who was also a volunteer. All used their GI bill to get an education.
My point being, there's tons of military jobs that don't involve violence. For each job that does require violence, dozens more auxiliary positions are required to support that job.
