United States Army Ordnance Munitions and Electronic Maintenance School

Its mission was to train military and civilians to safely disarm and dismantle explosives and repair and maintain electronics, missile and ammunition systems.

The OGMS greatly expanded through the years, occupying a large land area with many buildings and providing a wide variety of missile and munitions courses for thousands of students from the U.S. as well as many foreign countries.

The School Brigade administratively operated MMCS with subordinate companies for staff, faculty and students.

As the U.S. Army retired their major missile systems, OMMCS dropped the related training and was renamed to the Ordnance Munitions and Electronic Maintenance School (OMEMS) in 2002.

As part of the Base Realignment and Closure (BRAC) process the U.S. Army Ordnance Center and School was moved from Aberdeen Proving Ground, Maryland to Fort Lee, Virginia in 2009.
