Prior to 9/11, the obligation of the military’s Reserve Component servicemembers — more commonly known as reservists — was typically limited to training one weekend a month and two weeks during the summer. In support of the extended military engagements in Afghanistan and Iraq, however, reservists have been required to serve as full-time members of the military for prolonged periods of time. A rough calculation suggests that in about half of all cases, reservists spent a year or more serving on full-time military duty, with the average duration lasting eight months. The military has relied more heavily on reservists than at any time since the Korean War.
