I have tried looking online and I haven't seen anything saying that if a soldier wants to reup he/she needs a minimum GT of 100. Is this a real policy? My unit is going around telling soldiers this. I want to reup but my GT score is under 100, I have no problem taking BSEP classes to improve my score but due to family issues, I may run out of time and not be able to improve my score in time to reup. If this is for real, where can I see it on paper?
Without getting into the Regs and Milper messages that govern reenlistment I'll give you a short answer: It's the commander's decision whether or not he authorizes you to re-enlist. If it is his determination that an individual does not meet his qualifications then he can award those limited re-enlistment slots to soldiers he feels are "more worthy." Again, this is really oversimplifying the whole thing but its one aspect that might answer your question somewhat.
