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.

    Telemetry Surveys: Tracking Life Beneath the Surface

    Environmental manager Ashley Lopez, fisheries biologist David Colby, and Bryte Yard technicians deployed acoustic telemetry receivers along the lower Sacramento River to monitor juvenile salmon and green sturgeon migration patterns and habitat use. The data collected helps assess the impact of flood control projects like the Sacramento River Bank Protection Project on aquatic species. Shared with agencies such as the National Marine Fisheries Service (NMFS), the telemetry results support environmental compliance and guide mitigation efforts for federally protected species. This collaboration with partners like the California Department of Water Resources (DWR) and UC Davis ensures that flood risk management projects are balanced with environmental stewardship.
  • Cold War-era rolling pin barracks undergo vital renovation

    Soldiers marching in uniform, drill sergeants yelling, muddy obstacle courses – these are often the images the words “basic training” evoke. Hollywood and pop culture have helped ingrain the military’s grueling boot camp experience in the minds of the average person. Whether Hollywood’s depictions of basic training are based in truth or not, one thing is for sure: the soldiers who complete Army basic combat training are some of the toughest in the world. Tucked away amongst the dense forests and scenic lakes of central Missouri lies Fort Leonard Wood, one of four installations home to the Army’s basic combat training course. Originally built in 1940 as a small World War II training site, Fort Leonard Wood is now a premier training installation within the Army, the U.S. military and the world.
  • ERDC explores Nuclear Energy Systems to power future mission
