The Volunteer Reserves are the British Armed Forces voluntary and part-time military reserve force. Unlike the Regular Reserve, the Volunteer Reserves do not consist of ex-Regular personnel who remain liable to be re-called for military service. Instead, the Volunteer Reserves consists of civilian volunteers who routinely undergo training and military operations alongside the Regular military. The Volunteer Reserves serve under a fixed-term reserve contract and provide "highly trained" military personnel integrated with their Regular counterparts, on operations both at home and overseas. For example, almost every major military operation has seen the deployment of Army Reservists alongside the Regular British Army. Volunteer Reserves are allowed to use the post-nominal letters VR after 10 years of service.
