The unit was formed as II Armoured Car Company at Hellopolis, Egypt on 7 April 1922 and placed under the command of Squadron Leader M Copenan. The Company was equipped with Rolls Royce Armoured Cars and Morris Tenders, which it retained until 1944.  

1924 found the unit engaged in active operations against the Wahabl tribe who were causing unrest in Transjordan, then a British Protectorate. The actions took the form of a series of ground and air attacks against the fanatical tribesmen near the city of Amman. During the course of the battle II ACC captured one of Wahabi Tribe's coveted Banners.

The Company's second battle honour was won during the Palestine troubles 1936-1939, again enforcing British rule in the Middle East. They were involved in reconnaissance patrols and convoy escorts as well as joint operations with the Army.  

Throughout World War II the Company's expertise in Desert Operations, gained in the previous 2 decades, was put to good use. They fought in Egypt, Libya, Syria and Iraq perhaps most notably providing vital airfield protection during the battle of El Alamein. Throughout its time in the Western Desert the Company was in almost constant contact with enemy tank formations.  

II Armoured Car Company was incorporated into the RAF Regiment on 3 October 1946 and was renumbered 2702 Armoured Car Squadron. Undoubtedly due to the pressure from veterans, it was again renumbered to II Armoured Car Squadron on 25 February 1947. The Squadron continued to operate in Palestine until the British Mandate ended in May 1948.  

The unit moved to Iraq for the next 7 years and relinquished its Armoured Cars to become II (Field) Squadron RAF Regiment. From there it was on to Cyprus in 1955 and Malta in 1959, where the first Standard was presented on 25 November by Air Chief Marshal Sir Hubert Patch.  

On 1 October 1960 the Squadron arrived in the United Kingdom for the first time during its 38 year history. After a brief spell at RAF Felixstowe II (Field) Squadron moved to RAF Colerne in Wiltshire and adopted a Parachute Capability. Throughout the 1960s the Squadron was tasked with Internal Security Operations in Cyprus, Aden and Ulster. On 1 January 1970 the Squadron title changed again, this time to II Squadron RAF Regiment. In July of the same year Support Weapons Flight were present at Salalah, Oman, when Sultan Qaboos overthrew his father in a coup. Other detachments during this time included RAF Muharraq in the Gulf and Hong Kong.  

RAF Colerne was left in favour of Catterick in 1976 when II Squadron became part of 3 Wing, but within 4 years, the unit had moved back to Wiltshire, to RAF Hullavington. On 19 August 1981 the Squadron returned to the original Armoured Reconnaissance role when it re-equipped with CVR(T) and was assigned to support the Harrier Force in Germany.  

During the Gulf War in 1990, II Squadron provided Internal Security and Defence of RAF Akrotiris' Airfield until the return of 34 Sqn from the Gulf region..  

The 70th Anniversary of the Squadron in 1992 saw more changes, the demise of CVR(T) in the Regiment and the return to RAF Catterick. II Squadron also undertook further deployments to Northern Ireland.  

Today the Squadron is based at the new RAF Regiment Depot, RAF Honington. It retains its parachute capability and its readiness to deploy world-wide in defence of RAF Assets, primarily the Support Helicopter Force. The Squadron completed a 6-month operational tour in Bosnia in 1996 and was relieved in place by 34 Sqn in early 1997. Since then it has been deployed to Kuwait rotating with the other Field Squadrons as part of Op Bolton.
