A NEW CHAPTER: - Tuesday, August 5, 2025

On August 5, 2025, the U.S. Army Corps of Engineers officially realigned mission oversight of USACE operations in support of U.S. Central Command and U.S. Special Operations Command from the Transatlantic Division to the Southwestern Division. This transition ensures continued, focused support to U.S. Central Command and U.S. Special Operations Command across the Middle East, Central and South Asia, and the Levant. Both the Middle East District and the Transatlantic Expeditionary District remain fully operational and continue delivering engineering solutions that support regional stability and operational readiness. This is a new chapter, not a new identity. The mission – and the USACE legacy – continues.
