A financial year includes all outflows from 1 April to 31 March.

Length of Service is recorded when someone completes that month.

Specialisations have been excluded from these tables due to the need to protect sensitive small figures.

All totals are rounded in accordance with the Defence Statistics rounding policy. All numbers are rounded to the nearest 5 with numbers that would be rounded to 0 represented by '~'.
