Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many joint training sessions involving reserve and regular forces took place in each month in (a) 2014 and (b) 2015; how many (i) reserve and (ii) regular service personnel attended each such session; and if he will make a statement.

This information could be provided only at disproportionate cost.

The Royal Naval Reserve trains with Royal Navy Regulars and other Front Line Command regular forces on both joint exercises and training courses. Major joint exercises involving regular and reserve Maritime Forces include Exercise TRIDENT JAGUAR and Operation COUGAR, while joint training courses are routine business.

The British Army is now a fully integrated force. Every Army Reserve unit is paired with a regular unit, providing opportunities for joint training at both the individual and collective level. Over the last year, Army Reserve units with embedded Regular personnel have conducted 23 overseas training exercises in nine countries, including USA, Denmark and Cyprus.

As part of the whole force approach, the Royal Air Force aims to exercise in a joint regular/reserve environment as often as possible. Appropriate personnel participate in exercises, irrespective of whether they are regular or reserve.
