Sheila is one of the supporting characters of the Red vs. Blue series.
Background[]
Originally named F.I.L.S.S., Sheila is a vehicle-only AI behind the Blue Team's Scorpion tank built by an American automotive company and assembled in Mexico. Blue Team’s tank is a M808V Main Battle Tank. As a tank, her cannon is strong enough to destroy entire vehicles and kill any character with one hit if taken directly. She’s also very durable, being able to take immense damage before becoming inactive. It took an airstrike and a well thrown plasma grenade to stop her. For some reason, the tank has six pedals even though there are only four directions.
