Today, the U.S. Army Reserve celebrates its 106th birthday. Generations of Reserve soldiers have followed in the footsteps of servicemembers before them who embraced the nation’s call to duty by volunteering to serve as Citizen-Soldiers in the Army’s Reserve force. The Army Reserve is an important element in The Army multi-component unit force, training with Active and National Guard units so that all three components work as a fully integrated team.
The Army Reserve performs a complementary role to the Active component, providing combat support and combat service support functions to enable the Army to ramp up its capabilities to protect combat forces and sustain mobilization. The Army Reserve makes up only 20 percent of the Army’s organized units, but it provides about half of the Army’s combat support and a quarter of the Army’s mobilization base expansion capability.
