Might be ok, but it's impossible to tell from the website. Not nearly enough details, and not the clearest of wording. I'd go ask finance or personnel or someone at the MPF for some sort of instruction or regulation spelling out the nuts and bolts of the entire program. Especially so as to make sure that there aren't any hidden or unexpected clauses where taking the bonus extends your overall commitment beyond the year or something weird like that. There's always a bunch of strings attached to every dollar the military gives you.
