I earned my Army military retirement pay, even though my specialty by definition was a "non-combatant".
Soldiers (and Marines, Airmen, Sailors, and Coasties) do a hell of a lot more than get shot at, and the Services know a hell of a lot more than you ever will about what kind of personnel and specialties it takes to field and sustain the forces for National Defense and Power Projection.
By the way, ever heard of combat pay? hazardous duty pay? Combat zone tax exclusions? The personnel getting shot at already have some differential compensation available.
