In the military - those fuels are often listed in a squadron (or HHQ) SOP. For instance - our NATOPS lists 1,500# of fuel on deck. If you think that you will be on deck with less than that amount - declare EMERGENCY fuel and expect that ATC will handle accordingly. Minimum fuel is a fairly loose term for us. We all learn about it but it isn't a hard number often times. It means that any undue delay will probably drive me into an EMERGENCY fuel siutaiton. We are briefed not to expect any special handling from ATC, but a smart controller/pilot team will realize what is going to happen soon and usually there is some action taken to prevent the situation from deteriorating further.
