Don’t know about the policies now, but 9 of us who were in the
same squad in PA joined only after our BMT.
If I’m not wrong all of us actually applied before enlistment but
received our letters to late. Thus we had to complete our
BMT in the army before joining PA. Good and
bad points, one, you would appeciate the food more in PA, secondly,
you be a lot more fitter than your squad mates, in fact we out run
even our PTI/FI. But then you’ll be stuck for
11 bloody months as a chow recruit.
