shortest possible answer: So that you’re not involved in the next My Lai massacre or the next Kunduz Hospital airstrike
My father joined the US Army to provide healthcare to his family. As a result, he was directly involved in war crimes in Kosovo, where his battalion (101st Airborne) bombed schools and hospitals!
Nothing the US military can promise, be it healthcare, housing, “life experience”, travel, or tuition, is worth the atrocities you will be responsible for or complicit in.
