Foxtrot Uniform means fouled up — broken, messed up or not working as it should. It is one of the most recognisable military alphabet phrases — a pair of phonetic alphabet code words that stand in for an abbreviation.

Breaking it down
From F.U. on the chart: Foxtrot (F) and Uniform (U). It is the polite phonetic stand-in for calling something thoroughly messed up.
Where it comes from
Like most of these, it is field humour: a deniable, sayable way to label a plan, a piece of kit or a situation as fouled up, without using the unfiltered phrase in front of the wrong people.
How it is used

- Equipment: “The whole comms setup is Foxtrot Uniform.”
- Plan: “That timeline is Foxtrot Uniform — it never had a chance.”
