reservist bmt is like 5 days only loh.
i knew a guy whose pes B and ORDed without recourse either. he just
got lucky, the MO boarded him, but lost the paperwork, so he wasn't
downgraded. when he was called for BMT, he still had 2 weeks of
excuse left, he went down and they OOCed him on the spot. and then
he ORDed few months later.
