The United States Army Reserve

The United States Army Reserve is the federal reserve force of the US Army. Together, the Army Reserve and the Army National Guard constitute the reserve components of the US Army. It was formed in 1908 to provide a reserve of medical officers.

Reserve soldiers perform only part time duties as opposed to full-time soldiers, but may be called upon to do full time duty. They generally perform training or service one weekend per month and for two continuous weeks at some time during the year. Many reserve soldiers are organized into Army Reserve units, while others serve to augment active Army units.

All US Army soldiers sign an initial eight year service contract upon entry into the military. Typically, the contract specifies that some of the service will be served in the Regular Army, or active component, with the rest of the service to be served in the reserve component; however, some soldiers elect to sign a contract specifying that all eight years be served in the reserve component, in which case the soldier is entering directly into the Army Reserve. Those soldiers who serve a period of years in the active component and choose not to re enlist in the active component are automatically transferred afterwards to the reserve component to complete their initial eight year service obligation. After the expiration of the initial eight year service contract, soldiers who elect to continue their service may sign eight year contracts consecutively until they finally leave; however, some of these senior soldiers have the option to opt for an indefinite contact, in which case the soldier remains a part of the military until they retire, are removed from the service for cause, or elect to leave
