Check with your recruiter. I am surprised that you have not already gone down the list of MOS's to choose from other than being in the "Infantry" with your recruiter. If you have already signed the contract to be in the 'Infantry', that is where you will be until you have the opportunity to reenlist. Sometimes you can make a change in 'Boot Camp', but it isn't easy. There are many MOS's to choose from, which you should have already done with your recruiter.
