The Army Reserve powers the Army in any type of mission. From medicine to transportation; from engineering to civil affairs; from logistics to intelligence -- these are just a few of the specialized skills the Army Reserve brings to Army missions.

Much like the men and women who make up the Army Reserve, the specialized skills they perform are extremely diverse. Soldiers can be trained in almost 200 different Military Occupational Specialties. Many Soldiers bring extensive civilian training and experience to the Army Reserve, increasing the capabilities of the force. At the same time, Army Reserve Soldiers can often use their specialized military training to be more successful in their civilian careers -- to improve their current job, to help them get promoted to a better position, or to enter an entirely new industry altogether.

In general terms, Army Reserve Soldiers are the:

• OPERATORS who make things happen - medical, administrative, chemical, signal, military police, transportation, maintenance, supply services, civil affairs, psychological operations and public affairs.

• ENABLERS who provide the capability to respond to national emergencies anywhere in the world at any time - running mobilization stations and port operations, backfilling Active component units, garrisons, hospitals, and allowing training base expansions.

• TRAINERS who ensure that individual Soldiers and units have the skills to do their jobs - basic and advanced individual training, professional development, unit mission training and ROTC.

• STAFF OFFICERS who provide critical specialized and technical expertise - Individual Mobilization Augmentees and CS/CSS experts.
