Should I consider commissioning active duty even if it's not my original choice?

Gamble with trying to get AD but be prepared to get RC. Honestly, your GPA and APFT don't matter. It's about quotas. AD will select a quota from each school and give the rest to RC. They do give preference first. Though you may not get the branch you want for AD, there is a higher chance to get it if you choose RC. Like CPT Gabe Snell said, if you don't have plans for the civilian side, go see the world and gain experience on AD.

IMHO, I would go AD first to see what it is like, and after you get some experience, either stay AD or go reserves. I believe the time on Active Duty can only benefit you in the reserves.

Interesting. you are to be recognized for just being in a ROTC program and doing well academically. That generates options. Have spent time at several Army ROTC programs and West Point. Unless you have your sights on a particular civilian job why not go for active duty? Have to imagine you would have more learning opportunities and leadership development experiences going active duty. Also a chance to see if you want to progress towards a military career. We see much demand for five year officers in the civilian business world. You can continue to serve in Reserves or National Guard. Does that help?
