"i got a 3.2 on my fitrep in the navy am i in trouble?"
Probably not, because if you had to go to the Google to ask that question, then you probably are too junior for that grade to hurt you too badly. You're probably an ensign who has received his or her first fitness report. You have time to improve your performance. The critical selection boards are likely several years away and since it is not unheard of for butter-bars to trip over their feet a time or two, don't sweat it. (But don't make a habit of it.) I once knew an ensign who screwed up so badly that he almost wound up in front of a general court martial, but he survived his fuckup and did command tours both afloat and ashore.
But if you are a lieutenant and you've been an officer for at least four years and you're asking that question, then you need to have a good long talk with someone, and by that, I don't mean talking to the chaplain and getting a key to the Weep Locker. For while I don't know the current climate, back in my day, when the Navy had a lot more ships than it does now, for an O-3 to get a 3.2 on a fitrep was a subtle message that one should consider investigating another line of work.
(And if you are an O-3 and you don't already know the answer to the question that you Googled, that smelly stuff that you are neck-deep in is not kimchee.)
