In January, 2015, MARSOC completed its shift to regionalized operations when 2nd MSOB sent a company to support missions in the U.S. Central Command theater of operations, beginning support to Operation Inherent Resolve in response to the advances made by ISIS. This deployment officially aligned the three Marine Special Operations Battalions: 1st MSOB aligned to U.S. Pacific Command, 2nd MSOB aligned to U.S. Central Command, and 3d MSOB aligned to U.S. Africa Command.
