No. 2503 (County of Lincoln) Squadron RAuxAF Regiment is a Royal Auxiliary Air Force RAF Regiment reserve squadron based at RAF Waddington, in Lincolnshire,[1] fairly close to the city of Lincoln and RAF Cranwell. Gunners are recruited both from ex-regulars in the RAF Regiment and civilians in a 50 miles radius surrounding RAF Waddington.[2] The squadron is an infantry squadron in the dismounted close-combat force protection role.[3] The squadron consists of two Flights of RAF Regiment personnel and one Flight of RAF Police personnel.
The squadron was formed on 1 July 1979 at RAF Scampton[4] [5] to provide force protection to the Vulcans being maintained there at the time; in 1985, the squadron was moved to its current home to provide force sustainment for the regular RAF Regiment.[2] The squadron was deployed to Iraq during the Iraq War as part of Operation Telic, and gunners from the squadron have also been deployed to Germany,[6] [7] the Balkans, Kuwait and Afghanistan[8] as part of Operation Herrick.[3]
The squadron standard was presented on 6 December 2005, backdated to July of the previous year.[4]
In 2015, the squadron was tasked with assisting on an archaeological dig, searching for a lost spitfire.[9]
