Tim Burchett, center, the Mayor of Knox County, Tenn., holds a proclamation to commemorate the 105th birthday of the Army Reserve in Knoxville on April 23. He is joined by several Army Reserve soldiers and Army Reserve Ambassador for Tennessee John Dyess, third from right.
The Army Reserve originally started as the Medical Reserve Corps in 1908, but became an active military branch after World War I. The mission of the US Army Reserve is to provide trained, equipped and ready soldiers but also to help with aid after natural disasters and with civil support.
Today, more than 200,000 Americans are enlisted in the Army Reserve ready for combat when called upon.
