The squadron later saw service in the Second World War and today supports the 21st Engineer Regiment of the new 1st Strike Brigade.

The formation was part of the major expansion and numbering of the Corps of Royal Engineers following the Childers Reforms.

[1][2] In 1915, Sir Ian Hamilton proposed a planned invasion of the Ottoman Empire via the Dardanelles.

The company embarked from Gibraltar en route for Egypt where it joined the force later moving to Mudros that same month.

The company spent the entire war in Gibraltar providing support for the troops there and construction and maintenance of the defences.

[12][13][14] After moving to Alanbrooke Barracks in Paderborn, the squadron was assigned to the 20th Armoured Brigade for operational support.

[2][15][18][19] From 30 April—5 August 1971, the squadron saw a deployment with the 21st Engineer Regiment to Long Kesh in the infantry role.

Part of the changes was the elimination of titles e.g.; 20th Armoured Brigade became Task Force Hotel.

[2][18][20][21] After this minor change, the squadron deployed to Ballykelly in Northern Ireland from 23 June 1978—25 October.

From May—October 1993 the squadron deployed to Yugoslavia as part of Operation Grapple II replacing the 35th Engineer Regiment.

[26] From early 1997—September 97 the squadron deployed to the Falkland Islands and in 1998 on Operation Agricola I in the Serbian Autonomous Province of Kosovo.

Following the Strategic Defence Review of 1998, the squadron along with 21 Engineer Regiment again moved, this time to Roberts Barracks.

[2][31] Following the Army 2020 refines, the squadron is still part of 21 Engineer Regiment, now supporting the 1st Strike Brigade.
