Unit members were activated in late December 2001 and have deployed to several locations including Afghanistan, Iraq, South America, Africa, Germany and Fort Bragg, North Carolina.

In 2003, elements of the 153rd Finance Battalion, based in St. Augustine, Florida were mobilized to Guantanamo Bay, Cuba, in support of Operation Enduring Freedom.

Also in 2003, more than 340 Soldiers of the Jacksonville-based 146th Signal Battalion were activated for Title 10 duty and performed external security missions at six of Florida's Air Force bases stretching from Pensacola to Homestead.

The RCC performed flawlessly during the exercise and stands as the benchmark for partner nation intra-agency cooperation for targeting transnational terrorist groups throughout the region.

That feat delivered more than 11½ months of boots on ground time for the Army, and nearly matched the deployment length of active duty component units.

During this deployment, the Overseers were the proving ground for many new operational techniques that have produced an efficient and creative utilization of existing air traffic control (ATC) systems.
