History: In World War II III Corps served as a heavy corps
in the Western Europe theatre. Since then, the III Armored
Corps has become the US Army's principal armored reserve, assigned
to support NATO forces in Europe.
Current Status: III Corps currently has two active heavy
divisions, plus other combat and support units it controlls.
It is expected to deploy both in support of NATO's Central Front
and in support of other US units in the Middle East and elsewhere
in the case of a major war. While not listed here, III Corps also
supports a significant number of National Guard forces expected
to reinforce it in wartime.

This unit was originally a test-bed for a long range attack
helicopter strike unit, and was first to receive the AH-64 Apache
in 1986. It was a CENTCOM priority unit, but was unable
to deploy in Desert Storm due to a hurricane that struck Texas
in the Spring of 1990, damaging much of its aircraft in the process.
It currently has a forward task force in Korea to reinforce 8th
Army.
