The Briggs Tanks is one of the newest Amestrian technological advancements being designed and invented on the front lines of combat in the Briggs Mountain Range of northern Amestris. It is a new type of fighting vehicle with heavy firepower and defensive armour. The first mobile war machine of its kind, the Briggs Tank is highly maneuverable and can accelerate rapidly. It is protected by durable armour, presumably incorporating the various steel composite alloys also being developed by Fort Briggs' Research & Development department. The armour is light grey for camouflage. Armament consists of a turret mounted main gun and a machine gun in the bow. Small yet effective, the Briggs Tank has a crew of two, a driver and a gunner, but can carry up to three safely. Its first successful test run was in the winter of 1914 against a powerful unknown intruder invading the base from below. It also displayed reasonable success the following spring, proving invaluable to Briggs forces in subduing any threats they came across while moving toward Central Command, only to be overpowered by the Homunculus Wrath.
