The M2 Browning was created John Browning at the end of world war I and has been in service since 1921 up to the present due to its high versatility and fire power. It is the primary heavy caliber machine gun of NATO countries and its use in the JGSDF is no different.
It fires 12.7mm rounds, which are highly effective against most enemies the JSDF has encountered in the Special Region. 12.7mm rounds can be used against vehicles, lightly armored aircraft and non-fortified buildings. Thus, making it ideal against shields and armor used by soldiers of the Empire.
Despite this, the M2 Browning has difficulty going through normal sized winged dragons even with AP rounds and it is entirely ineffective against the Flame Dragon because of the tough scales that act as a natural armor for these dragons.
