The Queen's Royal Lancers was formed in 1993 by the amalgamation of two regiments: the 16th/5th The Queen's Royal Lancers and the 17th/21st Lancers.
From its formation, the Regiment served in an armoured role with first Challenger 1 and then Challenger 2 Main Battle Tanks. In 2005, as part of the re-organisation of the Army, the Regiment converted to a reconnaissance role, re-equipping with Scimitar armoured vehicles.
The Regiment's nickname, the 'Death or Glory Boys', comes from their famous cap badge which is known as 'the motto'. This is the combined cap badges of the two antecedent regiments, featuring a Scarlett backing from the 16th/5th Queen's Royal Lancers and a skull and crossbones with the words ‘or glory’ from the 17th/21st Lancers. The Regiment’s four Sabre Squadrons were each named after one or the antecedent Regiments.
On 2nd May 2015, the Queen's Royal Lancers amalgamated wth 9th/12th Royal Lancers (Prince of Wales’s) to form The Royal Lancers.
