Army: Manpower

Volume 486: debated on Thursday 22 January 2009

To ask the Secretary of State for Defence what percentage of each Army corps did not meet (a) harmony guidelines for tour intervals and (b) separated service guidelines in each year since 2001. (249701)

Historical data to support the percentage calculation of breaches in harmony guidelines for tour intervals and separated service guidelines for each Army corps in each year since 2001 are not held centrally and could be provided only at disproportionate cost.

The percentage of each Army corps (for which we record tour interval information), failing to meet harmony guidelines for tour intervals, as at December 2008, is:


Percentage breaching harmony guidelines

Royal Artillery


Royal Armoured Corps




1Excludes 2 Royal Tank Regiment as it has not deployed as a formed unit since 2003.

2Excludes 1 and 2 Lancs due to their amalgamation (1 Korbr, 1 Kings and QLR) in 2006.

The unit tour interval is a less relevant measure when applied to other corps (such as Royal Engineers and the Royal Corps of Signals). This is due to the frequency with which personnel move between formed units within these corps (the personnel deployed with a unit will be substantially different from the personnel deployed with the same unit on a previous occasion). Unit tour interval data for these Corps are not, therefore, routinely collated.

The latest available data (as at December 2006) recorded separated service guideline breaches at an average of 10.3 per cent. across the Army. It is hoped that separated service data will, in future, be provided by the Joint Personnel Administration System.
