One of the most difficult things that I encountered at FT. Benning was the week I was at 30th AG. When you get to your training unit just take it one day at a time. remember its just 14 weeks, and honestly BCT isnt a test of what YOU can do but how well your platoon works as a team. That is the largest issue with new soldiers coming in, they do not know how to work as a team.
Bottom line is, OSUT is designed to make you fail no matter what, even if you do everything and accomplish all your tasks above standard. You will always fail according to the Drill Sergeants. It is designed to break you down and then build you back up. Dont quit and give it your all. Those 3 1/2 months will go by and it will be over with before you know it.
