rebroadcast det, used to join two radio nets together for technical (range/obstructions) or tactical (electronic warfare) reasons
see Army Air Corps
usually the best det to be on in peace and war, peace time exercises means lots of freerunning to distant locations well away from the rest of the BattleGroup, lots of eating banjos and drinking brews and remoting into a local pub for a liquid lunch
war time is lots of fun, with the head shed flapping about force protection,
R Signals rebro dets are the detachment of choice. When placed on a high feature in an operational environment, siting is always taken account of HLS in order to allow resupply of copious quantities of local pivo.
