I commend you for your thoughts of enlisting. I’ve been there-done-that myself. Keep in mind you will be competing with kids almost half your age with a much different view of our culture than you might have.
The combat arms can be quite physically demanding.
Where I’m going with this, is go into an MOS (job) where your age is more apt to be respected, say maybe an MP, CID investigator or one of the many military intelligence jobs.
Being an officer is a great idea, but keep in mind if you go that route you will be in competition smart a$$ butter bars. Instead, find a job as a warrant officer, I found older warrant officers are well respected as a W01.
I’m not gonna be a lifer or anything. I just need an enlistment bonus to help my wife and crippled brother. I plan on sending all my money home. I’m the wrong color to work this close to Mexico. Whites are trash down here in Brownsville.
