Do you have any suggestions for things to study or know before going to 13F AIT?

Observer Target(OT) Direction, Danger Close, Trajectory, Method of Fire, Distribution, Projectile, Fuze, Volume, Deviation Correction, Range Correction, Height of burst(HOB) Correction, Target Description, Mission Type/Method of Control, Splash, Repeat

Memories these in order. You’ll learn what they mean when you get to Oklahoma.

Good luck! Hopefully you end up in an infantry unit.

I was an 11C. 13F were, and still are, some of my best buds.

I’ve found that going in blind is sometimes a good thing on academically intense courses. Like not developing any “bad habits” beforehand. Just show up and let them teach you. The curriculum is is designed to set you up for success......let it do that by not getting ahead of yourself. Good luck!
