Same here, hadn't flown a hawk in about 3 years when I got the type. Some FSDO require 10 hrs PIC, or 10 PIC within 12 months, but ours (Albany) does not.
I believe any mil equivalency will be only to commercial level - you have to take an actual checkride to get typed with ATP privileges. Others may know better.
