The 72nd Studies and Observations Group, better known by its call-sign Devil's Sons, is a joint-service special operations unit attached to the special operations frigate SVFF Barb, and is commanded by Lieutenant Commander Damien Daniels. The unit was spun off from the legendary Beaumont's Raiders in 3268 and has maintained its original mission as a special direct-action and clandestine activity unit, primarily staffed by Marines and Naval Infantry, though it contains a few Army special forces operators and Air Force paratroopers. The unit survived the reorganisation of the special forces after the Great War, in which its parent unit the 9th Joint Special Forces Brigade was demobilised.
