The following are events related to the Global War On Terrorism (GWOT) that took place on this day.

2001

• The Marine Corps released its proposal to set up a brigade-size antiterrorism unit that would, because of its size, be more effective against overseas or domestic terrorist threats. Since the terrorist attacks of 11 September, the U.S. military faces restructuring in preparation for a unique war against unconventional enemies. The proposed unit would be made up of an existing infantry battalion, reinforced by members of the Marine Corps Security Force Battalion, the Marine Security Guard Battalion, and the Chemical/Biological Incident Response Force, each bringing a measure of expertise. Once trained and equipped, claimed a Marine official, the brigade could deploy in seventy-two hours.

2007
