Enclave Squad Sigma

Enclave Squad Sigma is a special operations unit of Enclave soldiers. stationed at the mobile base crawler in 2277.

Background
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 their share of combat sorties and lived to tell about it. 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. Each member of a Sigma squad is a veteran of numerous combat sorties, trained in multiple forms of combat. Organized into six-person squads, Sigmas are the highest trained and most experienced troopers the Enclave has to offer.

Daily schedule
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, except the leader, who idly wanders around the Mobile Base Crawler area.

Quests
