The Westminster Dragoons (WDs) are central London’s only Army Reserve cavalry unit. One of the Royal Yeomanry's five squadrons, their current role is light cavalry: to provide a rapidly deployable force with fast mobility and substantial firepower in support of operations.

Formed in the aftermath of Second Boer War as part of the County of London Yeomanry, the WDs fought in the Battle of Gallipoli and led British forces onto the beaches during the Normandy Invasion in 1944. The squadron most recently saw action on Operation Telic, when it was mobilised for the 2003 war in Iraq and again in 2006 for peace support operations there. Since 2007, soldiers and officers of the squadron have deployed as individual reinforcements on Operation Herrick in Afghanistan.

The Germans planted over four million mines along the French coast to hinder the Allied landings in 1944. To break through these defences at the start of the Normandy Invasion, the British produced a number of novel armoured fighting vehicles under the ingenious direction of Major General Percy Hobart, including the Sherman Crab. The Crab bore a rotating drum with dozens of chains attached; these detonated mines in its path to produce a beaten passage through the thickest of minefields. The WDs were trained in this vital task, as part of 79th Armoured Division, led by Hobart. Along with 81 and 82 Squadrons of 6 Assault Regiment Royal Engineers, B and C Squadrons of the Westminster Dragoons were the first units to land on Gold Beach on D-Day in the British sector,learing paths off the beach and using their tank guns to destroy defences holding up the assault;[some three hours later further flail tanks of A Squadron landed in support further east on Sword Beach. The regiment went on to fight across Northwest Europe and into Germany.
