Army harmony guidelines are that individuals should not exceed 415 days of separated service in any period of 30 months. At unit level, tour intervals should be no less than 24 months.

The decision on who should deploy is made by Joint Commitments in consultation with Headquarters Land Command, ratified by the chain of command.

Royal Navy harmony guidelines are that no individual should exceed 660 days of separated service in a three-year rolling period. Over a similar time span, ships or other units should not be deployed for more than 60 per cent. of their time.

Harmony Guidelines for the RAF are based on formed unit tour intervals rather than individual personnel, whereby formed units, or sub-elements within them should spend four months on deployed operations followed by 16 months at base.

The RAF Individual Separated Service assumption is that an individual should spend no more than 140 days of duty detached away from home in a rolling 12-month period. This allows for a four-month operational tour followed by three weeks of separated service due to routine tasks, unestablished commitments, unit assistance, pre-detachment training etc.

These are guidelines only and there will be shorter tour intervals where operational demands require it.
