Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what proportion of (a) Army, (b) Royal Navy and (c) Royal Air Force personnel of each rank have been in breach of their harmony guidelines in each year since 2010.

The “Harmony Guidelines” are used by the Services to strike a balance between deployment, training and time with families. Individual Harmony Guidelines (IHG) are different for the three Services, equating to no more than 660 days away from home over a rolling three year period for the Naval Service, no more than 415 days away in a 30 month rolling period for the Army and no more than 280 days away over in the previous 24 months for the Royal Air Force.

The tables below show the information available in respect of breaches of harmony guidelines, by percentage in each year, by rank, since 2010 to the latest date available (1 January 2014 for the RAF or 1 March 2014 for the Naval Service and the Army).
