Charlie Company is coming home. Detachment Company C 1st Battalion, 23rd Marine Regiment based in Harlingen, has been on the front lines in the War on Terror since being called up in June 2004. The Marine Reserve unit, based in Houston, includes more than 80 Rio Grande Valley residents. One of them is Sgt. Ben Christensen, a Laguna Vista resident who was a Brownsville Herald sportswriter a decade ago. Christensen has sent dispatches from the front lines since October, and today discusses the unit’s deactivation. Charlie Company is scheduled to return this month to 29 Palms, Calif., to demobilize, and from there the Marines will return home in April or May.
