+1 to all the advice, with a few add-ons. Caveat 1: I'm not 100% familiar with Army Guard, but I'll bet it's pretty similar to ANG.

Reference your color vision. If ANG is where you want to go, don't give up on this just yet - remember: for every regulation there is an equal and opposite Guard waiver. You may get the "no," but it's worth asking.

For Guard, go VFR-direct to the unit you want to fly for. Don't stop at any recruiter. It may be that enlisting in that unit is the normal track for selection - a lot of units hire the lions share of their UFT folks internally, but even in units like that, they'll go outside for the right candidate.
