The most recent tour intervals for the Household Cavalry and the Royal Armoured Corps are set out in the following table.
Unit deployed Last operational deployment (as a unit) Start date Previous operational deployment (as a unit) End date Last unit tour interval (months) Household Cavalry Regiment1 Afghanistan October 2007 Iraq October 2004 35 Queens Dragoon Guards Iraq May 2006 Iraq April 2005 12 The Royal Scots Dragoon Guards Iraq November 2005 Iraq June 2003 28 Royal Dragoon Guards Iraq December 2007 Iraq April 2005 31 Queens Royal Hussars Iraq May 2006 Iraq April 2004 24 9th/12th Royal Lancers Iraq November 2005 Iraq April 2004 18 Kings Royal Hussars Iraq June 2007 Iraq October 2005 19 Light Division1 Afghanistan April 2007 Iraq October 2005 17 Queens Royal Lancers Iraq November 2006 Iraq October 2004 24 2nd Royal Tank Regiment2 Iraq March 2003 n/a — — 1 Subunits from Household Cavalry Regiments and Light Division have deployed in support of operations. The deployments listed are the unit deployments, defined as a regiment deploying with a regimental headquarters and more than two manoeuvre subunits for four months or more. Only the unit deployments will be included in the calculation. 2 2 RTR last deployed as a unit on OP TELIC 1 (March 2003—June 2003). MOD records date from January 2003 and therefore we have no record of any unit deployments prior to Op TELIC 1.
The unit tour interval is a less relevant measure when applied to The Royal Logistic Corps. This is largely due to the frequency with which personnel move between formed units within these Corps (which means that the personnel deployed with a unit will be substantially different from the personnel who deployed with the same unit on a previous occasion). Unit tour interval data for this Corps is unrepresentative and therefore not routinely collated.
