The United States Central Command (CENTCOM) announced on Saturday a task force to prevent Iran from using ground routes to transport advanced weapons and other materials.

Task Force Iron Gate is based in Tampa, Florida, and will operate along Iran’s land borders and the Caspian Sea, coordinating with other US government agencies against advanced weapons systems, dual-use technologies, sanctioned materials and illegal revenue streams. CENTCOM Commander Admiral Brad Cooper said the unit reinforces “the success of our ironclad blockade against Iran at sea.” Cooper directed the formation of the task force on November 7; it comprises about 20 civilian and military personnel. According to CENTCOM, the naval blockade has prevented Iran from exporting more than $25 billion worth of crude oil in recent months.
