Posted to previously unknown and highly secretive locations outside of the Capital Wasteland, only the most veteran of Enclave forces trained in multiple forms of combat earn the right to call themselves Sigma. These six-person squads feature a leader clad in Hellfire armor and carrying an incinerator. Each member has seen numerous combat sorties and lived to tell about them. Sigma Squads are posted around locations deemed by Enclave High Command as “imperative” to the salvation of the cause.
The Sigma Squad is assigned to protect the crawler in case of attack. It consists of 5-6 soldiers with different types of specialties, led by the Enclave Sigma Leader.
They are initially stationed in their sleeping quarters above the entrance to the Enclave Mobile Platform, but will proceed downstairs once the alarm is triggered to seek and destroy the Lone Wanderer. If the player manages to hide from them, the squad will retire back to their quarters upstairs, sans the leader, who idly wanders around the Mobile Base Crawler area.
