General Mission

The U.S. Army Test and Evaluation Command (ATEC) Headquarters is located on Aberdeen Proving Ground, Maryland. ATEC HQ’s eight subordinate organizations are located throughout the continental U.S., to include Arizona, New Mexico, Maryland, Utah, Texas, and Alabama. ATEC serves as the Army’s independent tester and evaluator, while in direct support of the U.S. Army Futures Command, to inform Army senior leaders and enable future Multi-Domain Operations. ATEC upholds its vision to determine the true capability provided to our Soldiers through developmental, integrated, and operational testing evaluated in an independent and objective manner.

ATEC was established October 1, 1999. It was the result of consolidating developmental and operational testing under one umbrella organization. Since then, ATEC maintains the responsibility to test and evaluate numerous pieces of equipment before fielded to Soldiers. This involves highly accurate and precise instrumentation to test sophisticated military systems under controlled conditions at testing facilities located around the country.
