I've seen the opposite -- I'm getting applications from current or recent ex military guys looking for 30%+ above the average salary for the position because they are grossing up to compensate for losing the tax benefits.
BIG part of it I have to consider after my military time is over is that a good chunk of entitlements are in the form of non-taxable "allowances." Many separated military people don't understand how much their salary needs to increase to compensate for the tax benefit we receive.
