They will continuously try and shimmy you into rolls they want you in, not the one you want to be so make sure you pay attention, also read ALL THE PAPERWORK, when I went to meps they screwed up my enlistment time and head it set for 4 instead of 3 years.... no joke shit like that happens and once all this shit is signed they've got you by the balls.
Also never get rid of any of your army paperwork that's about you wither it's a receipt or a copy, buy yourself a nice big fancy sectionalized folder, and turn that into your love me book. IT WILL SAVE YOUR LEGAL ASS!
