After Action for Incident FS-87,
Victims include 4 NCR Militiamen - squad was most likely on an unregistered patrol as they were not being observed until after the attack. Assailants believed to be raiders (likely Great Khans) with hunting dogs (two dog corpses were left in the scuffle - tracks suggest as many as a dozen in the attacking pack).
Threat Assessment: Trivial. Great Khans with dogs present virtually no matter of trouble. Incident likely caused by unskilled NCR patrolmen failing to radio us for an eyes-on backup.
Radioed HQ with report at 12:40, received Hanlon's confirmation at 12:42 that he received the details.
