Tim Burchett, right, the Mayor of Knox County, Tenn., shows a picture of his father as a young Marine taken in the Pacific during WWII to Army Reserve Soldiers in Knoxville on April 23. Sgt. 1st Class Brian Heller of the 489th Civil Affairs battalion and 1st Lt. Anna McDonald of the 844th Engineer Battalion joined other Army Reserve Soldiers in the Mayor's officer to commemorate the 105th birthday of the Army Reserve.
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.
