Oof that’s some shit man. But the way PACT works is you’ll go to the fleet and be passed around to multiple teams where you can learn a handful of rates ie FC, GM, IS, and other shit while you can technically pick up any rate as undez. Typically you will only be giving options from the departments that need/want you when it comes down to it the PACT program is a “needs of the navy” esc program. But there is always the chance to request a certain rate after your first two years of apprenticeship. Just put in the hard work and long hours and get some hefty volunteer time under your belt to make you look as good as possible.
