The regiment was formed in November 1992 by the amalgamation of The
Queen's Own Mercian Yeomanry and The
Duke of Lancaster's Own Yeomanry as part of the
Options for Change. In 1999, it absorbed a squadron from The
Queen's Own Yeomanry, bringing it to a strength of four squadrons plus the headquarters squadron. In October 2006, the RMLY became a single cap badge regiment, when the individual cap badges of each squadron were replaced by the newly designed RMLY cap badge. This incorporated the Mercian Eagle from the Queen's Own Mercian Yeomanry with the Red Rose from the Duke of Lancaster's Own Yeomanry. This was also the point at which H-Det joined the regiment, to provide a Recce troop. H-Detachment was renamed Manoeuvre and Support Squadron in 2011, when it was given Squadron status; it still consisted of the Recce troop, but now also housed the "hoop" (communications for the squadron). In July 2013, it was announced that the RMLY would be restructured under the
Army 2020 plan. A Squadron and B Squadron resubordinated to The
Royal Yeomanry, while C Squadron and D Squadron resubordinated to The
Queen's Own Yeomanry. The regiment was disbanded in April 2014. ==Organisation==
