The success rate is high because you are trained by the brst NCO's possible. There are some people that do not make it through because of injuries or something wrong psychologically. Also there are some people that do not make it through because they figure out they do not really want to be there. Basic prepares you for military life. It instills loyalty, duty, selfless service, honor, integiry, and personal courage. There will be some things that are easier for you than others and some days you will be wondering why you signed your name on that dotted line. Bottom line even though it may not seem like the DI's really do care about you and they are going to do everything in their power to help you become a soldier. Hope this helps.
