The only problem is that if you don't finish OCS and commission (which could be do to a physical issue that is no fault of your own) the loan jumps to some astronomical rate and you are can be considered in default. There's probably a slim chance of that, but there's still a chance. You will get payed more than enough to cover all of your uniform and other expenses at OCS, and your uniform bill is not due until sometime (6 months?) after you finish OCS. If you are going to take the loan take it for other reasons, 'cause that ain't a good one.
