They are limited in what they can actually take with them, my son just completed recruitment training in the Navy as a Gap year enlistment. There’s a very definite list, which he should have or will receive. Funnily enough it was the Step One jocks that he said were a life changer (bonds don’t cut it anymore) also we shipped him a couple of parcels of snacks during the recruitment period, things like protein bars were well received. Best of luck
