If you are looking to get commission, I have the following advice:
1) Have nothing to do with the enlisted recruiters – don’t even use them to find the appropriate path to getting a commission. I’m saddened to say my experience with enlisted recruiters suggested they were outright liars, and they made getting in touch with the appropriate person to become an officer much more difficult than it would have been had I simply used the internet. I assume there are exceptions, but many other people have had similar experiences as me.
2) Be ready for an involved process. The application is ginormous and they want many things, including lots of character references. It’s not difficult – being aware that it can be a long process is half the battle.
3) Do some research on what you’ll actually be researching. Some of the AF research programs have been shut down (is COIL still active at all, for instance?), so you might find yourself doing something you didn’t intend to do.
Best of luck, and do let us know how it goes.
