AV8R737,
Since you're from the states and asked about "4-6 months" of training, I assume you're refering to DEFO. If so, since you will be based in N.A., you'll receive per diem the entire time while training in Hong Kong. Enjoy.
I think our friend from Dirka-dirka-stan is thinking about DESO training. Put a jihad on him!
As a DESO you can check out of the Headland at anytime you like and begin receiving up to 21000 in housing. No per diem required. The lump sum of per diem handed out to SO's in Adelaide covers one weekend of solid binge drinking.
