Since 2010 more than 10,000 Reservists have been mobilised in a variety of roles on operations worldwide including Iraq, Afghanistan and the London 2012 Olympics.

As at 28 February 2015, around 400 Reservists are mobilised. More than 60 Reservists have been mobilised so far to assist in efforts to resolve the Ebola crisis in Sierra Leone. The majority of these are Army Reservists filling medical roles in the Kerry Town Treatment Unit and who I saw depart the UK last December, from Brize Norton.

The Secretary of State for Defence, my right hon. Friend the Member for Runnymede and Weybridge (Mr Hammond), announced on 29 September 2013 that recruiting for the Joint Cyber Unit (Reserve) would commence in October 2013. I can confirm that recruitment is well under way for this new unit and the large response it has elicited is extremely heartening. The details of their numbers, ranks and positions, must be withheld for the purpose of safeguarding national security, but I can confirm that the eventual strength of the Joint Cyber Reserve will number in the hundreds of personnel. I would also stress that cyber security is the responsibility of all personnel within the Ministry of Defence, and we are taking action to mainstream it into the way we conduct operations and business.

[holding answer 11 February 2013]: The Ministry of Defence ran a public consultation from 8 November 2012 to 18 January 2013 during which all employers, trade unions and other organisations were able to comment on our proposals for the future reserve forces. This included a comprehensive programme of national and regional workshops with employers of all sizes. We received a significant number of responses from reservists, employers and a wide variety of organisations. A full summary will be published alongside the White Paper in the spring.

[holding answers 1 and 5 February 2013]: The Navy's Maritime Reserves (Royal Naval Reserve and Royal Marines Reserve) were at a total strength (trained and untrained) of 2,570 at 1 April 2012 and will grow to a trained strength of 3,100 by 2018.

The Territorial Army was at a total (trained and untrained) strength of 26,640 at 1 April 2012 and will grow to a trained strength of 30,000 by 2018.

The Royal Auxiliary Air Force was at a total strength (trained and untrained) of 1,360 at 1 April 2012 and will grow to a trained strength of 1,800 by April 2018.

A comprehensive statistical breakdown of Reserve strength is provided through Tri-Service Publication (TSP) 7 which can be accessed at the following website:

Figures as at 1 April 2013 will be published on 23 May 2013.

Interim targets are subject to ongoing consideration in light of the recent Green Paper consultation.

[holding answer 1 February 2013]: Information on the number of joint exercises involving Territorial Army and regular forces conducted over the last seven years is not held in the format requested. However, many Army units have reserve and regular forces as part of their structure and conduct integrated exercises as a matter of course.

As the Secretary of State for Defence, my right hon. Friend the Member for Runnymede and Weybridge (Mr Hammond), said in his statement on 8 November 2012, Official Report, column 1025, on Future Reserves, reserve units will be paired with, train with, and achieve the same standards, as their regular counterparts. They will also deploy routinely, together with regular forces, on major overseas exercises.

In the future the Army will be planning for approximately 13 major exercises per annum both in the UK and abroad. These exercises are each expected to have over 500 participants. Reserve elements will take part in these exercises operating alongside regular units. The level of integration will depend upon the units involved, the requirements of the exercise and the scenario upon which it is based.

The information is not held in the format requested and could be provided only at disproportionate cost.
