The following Defence organisations currently use Airwave handsets:
British armed forces units based in the UK mainland (for operations, security, policing, health and safety purposes);
MOD Police and Guarding Agency (MOD Police and MOD Guard Service);
Nuclear Accident Response Organisation (NARO) (covering all MOD nuclear sites).
In addition, allied forces based in or transiting through the UK mainland with functions identical to MOD organisations that use Airwave handsets could potentially use Airwave handsets in the future. Airwave might also be used in the context of military prisoner transportation, armaments transportation and Defence medical services.
