Soldiers can serve in one of two ways: as a full-time active duty service member, or as a member of the Army Reserve. Both options have their own advantages.
serving full time
Active Duty is similar to working at a full-time civilian job. You will have your own Military Occupational Specialty(MOS) and you will fill a specific role within your unit. Your length of service may range from two to six years.
The Army Reserve enables you to pursue your civilian career or college education while you train near home and serve your community. Many professionals, as well as college students, are Soldiers in the Army Reserve.
