Had a few in years past and concur with the previous replies. Obviously it depends on the time available; my shortest was "Red 2 has been hit, might have to eject!"
Nice one was from a formation of Buccs(?) running in to break at Brawdy when the earth was cooling: - Sound of panting followed by: "Red 3 has just hit Red 2!!!" Followed by a slightly frustrated transmission from Red Ldr - " Oh Red 3, stop hitting Red 2!"
