On my Black Ops Weapons article, I claimed that an underbarrel flamethrower never existed. However, one of our readers alerted me to a model that existed as early as WWII. Created by the Finns, it was an underbarrel mount for the M44 flamethrower which was used on the Suomi KP/-31 submachine gun. While not entirely like the underbarrel Flamethrower found in Black Ops, this proves the concept still has some basis in reality. Thanks!
