How do you feel about military service?

Leaving next week for navy. And boy, I’ve had some interesting conversations about it. Old people tell me that I’m lucky trump is president, so I don’t die at war? Young people tell me I’m helping the rich take from other countries and others have said I’m gonna get PTSD. I literally just want free college and want to leave my small town. I’m getting trained in aviation maintenance (my dream is to get my A&P and go to college for electrical engineering) I don’t think joining is that big of a deal, it’s kinda like a job, but they throw you in jail if you’re absent. Also, considering my state’s economy, I’m getting a HUGE pay increase and COL increases.
