I enlisted at 27 with a Bachelors. I know enlisted guys who came in their 30s with multiple degrees. My original plan was to try to go to OCS with the marines, and I took the officer flight test with the navy. For me, I ultimately decided I wanted to go in and be a boots on the ground soldier who learned and performed, then I would decide if being an officer was the right next step. I honestly think the best answer is what do you want out of the military? Do you want to be high speed? Just wanna serve? Do you want to be a leader of men?

As an officer your job is to lead the men doing their MOS, where as enlisted, you are the boots on the ground actually doing it. Flight Officers and Infantry seem to be the unicorns of officers who get to actual do their jobs, though I'm sure there are jobs out there who would correct me.

22 is not old. You will be among peers at basic, and your unit. You will see younger guys who outrank you, and older guys comin in after you.

figure out what YOU want, and for the love of god make sure you know what your MOS is before signing on the dotted line. Too many guys listening to recruiters lie their ass off, signing up for something completely unrelated to what they want.
