It's probably like my Det's "Preflight". It's usually nothing intense, just busy activities to get you acquainted with your fellow GMC and POC leadership before school starts. If you want to get ahead, just research the AFROTC website and start picking up on these terms and acronyms, maybe even do some research on basic marching skills. You can find an Air Force Drill and Ceremonies manual online and scope it out if you are really bored, otherwise you'll learn all that during the semester. To be honest, AFROTC is kind of a crawl, walk, run type of program. Depending on how involved you are that can get mixed up, but it's up to you.
