Got randomly paid today by dfas

Woke up to 1274.47 randomly today paid out by DFAS. not sure what it’s for I know not to spend any of it until I confirm that I am in fact entitled to it. Just wondering what yall guess’s would be for what it’s for. I got back from deployment in July but already got paid out for my travel voucher. I hit two years this past month in November but no way this is a clothing allowance right? Anyways I’ll take a baconator and a frosty.
