Speaking as someone who joined the Marine Corps and deployed twice (once on a MEU and went to Iraq prior to OIR and another to Africa for the south Sudanese civil war crisis) I would have never done it knowing how things would have gone and how my life would be afterwards.
I have to live with the memory of those lives I helped end and ruin and the lives of my friends who were cut short by suicide, accidents and combat.
My mentality going in was “if I enlist then maybe in some strange cosmic statistical way some other young man can be home with his family and not have to sacrifice anything and they can lead a meaningful life.”
My life is practically in ruins by my own hand and mental/emotional issues that came from my choices.
Do what you think is right is the only thing I can say to you. All I can do is tell you what my sprain is like to help you get some context
