Briggs Tank

Among the technological advancements being designed and invented on the front lines of combat in the Briggs Mountain Range of northern Amestris is a new type of armored fighting vehicle called a "tank". The first mobile war machine of its kind, the Briggs Tank utilizes mechanized, armored treads for movement, is able to turn 360 degrees and move at ramming speed, is encased in a durable armor presumably incorporating the various steel composite alloys also being developed by Fort Briggs' Research & Development department and is armed with a positionable heavy artillery cannon. Small and durable, the Briggs Tank is operated by two soldiers, one for mobility and one for artillery fire, 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 and it also displayed reasonable success in the following spring, proving invaluable to Briggs forces who had gone to subdue an enemy in Central City.

Trivia
