I am thinking pretty seriously about serving as an officer in the Army. I am 22, turned in August, and will have my Masters in Economics this May. I have talked with a recruiter, taken the ASVAB, and looked at a lot of information online (here, army.com, armyocs.com, etc). I talked about with my family, and that went well. I just want help getting a very accurate picture of what I am commiting to. The whole reason I want to go is to help. I want to keep people alive. So I will have no bones with being genuinely humble and entirely grateful for any/all knowledge I can gain from NCO's and anyone who knows anything I may come across along the way (in boot and onwards). I don't know that alone will make me a good officer, but I want to do what I can do to my job well. My 3 major questions are: What is my realistic commitment? I know it is 3 years active duty and I can do the other 5 IRR, but I am 22 now, I will graduate in May, I have to train for what? A year? (boot, ocs, and mos training?) So really my commitment is 4 years? I want to serve in Iraq or Afghanistan. If I am not going to serve there, then that changes my incentives for joining. How much control over that will I have? How much control will I have over my MOS if I come out of OCS? My last question is a phsyical concern. I was always an endurance athlete in high school. I had a decent mile (4:40), obviously I am not in that shape constantly, but I could certainly get it down around 5 in a few months. I played water-polo, but once again, my strength was always endurance, never any great amount of brute strength. Is that going to make things more difficult for me? There is no point in commiting to being in Infantry officer, which is what I am looking to do, if I am going to get pwned in Ranger School because I can't max out on push-ups like some guys do. I am not gangly or anything, 6'2" 195 lbs, but I have always been more of a runner and a swimmer than a weight lifter in terms of my physique. Any help on these would be really appreciated. It is a big decision for me at this point in my life, as it obviously was for everyone serving now. Just want to make sure I make a good decision.
