The Long Night
Erasure squads are cleanup personnel. They are called into action if sentinels fail to deal appropriately with a situation and the threat is moving beyond control. If the watchword for a sentinel is “unobtrusive,” the watchwords for an erasure squad are “overmatched firepower.” If activated, the time for a subtle solution is passed, and they will use whatever means necessary to resolve the situation. If that means nuking a settlement from orbit to annihilate a nanoswarm and keep it from escaping to a larger settlement, then so be it. After which they’ll use every trick in Firewall’s bag to erase any evidence they were there and to place the blame for the incident squarely on the shoulders of some other party. If necessary, erasure squads can also be called in to fix a sentinel op that has turned into a clusterfuck or otherwise gone south. They are very careful to avoid exposure in such situations, however, which sometimes merely means eliminating all traces of Firewall involvement and letting the sentinels take the fall for their poor choices.
