Depending on where you get your figures from, somewhere between 80-85% of the jobs in the US military are non-combat, where there is as little risk of losing a limb as there is going about your day-to-day civilian life and losing a limb in a car crash.
If you didn't find something in your breadth-but-not-depth high school studies that grabbed your interest to the point where you decide that it's worth pursuing a four-year college commitment to study it in further depth, I struggle to understand how twelve months in a minimum wage job (a repetitive daily routine that affords you little if any spending money) would help clarify a direction.
