West City

West City and its surrounding areas are probably the most unknown parts of Amestris. What little is known is that it's locked in a constant struggle with the bordering nation of Creta. The West Military seems to have a strong affiliation with Central's, as in the latter chapters of the manga, it is the only other military group to come to Central's aid during Roy Mustang's coup d'état.

Western military forces are also said to have an impressive amount of troops, all adept in guerrilla warfare.
