Army PT Failure and over weight chapter benefits.?

Okay I have been in the Army for 4 years and have never had a problem with being overweight. I have struggled with PT ever since I have joined the Army. Im extremely hard working and really good at my job. Although it was not was not right, my chain of command has always turned the other cheeck because I made them look really well when it come to Table VIII and Table XII... Now im in a new unit, deployed to Kuwait, and this unit is talking about chaptering me. I am currently 1 % over body fat and I cant seem to shake it off. I have been trying. I am currently and always have been struggling with my push ups and failed the last PT test. I only have one year left before I get out, and I really need the benefits for college because I wont be able to to go to college on my own outside the Army. What kind of benefits will I get If I get chaptered for what they are trying to get me for!
