The Panzerknacker's name is derived from it's outstanding armor-piercing capabilities, both with the 34 mm HEAT grenades and with armor- piercing ammunition in its 4.85 mm barrel. Its primary feature is the extreme rate of fire, possible only because of the caesless ammunition mechanism. Folding stock and detachable grenade launcher.
(PANZERKNACKER means "TANKBUSTER" in english).

DRAGOON KAMPFKANONE
When the need arose for a more powerful weapon than the regular Panzerknacker Assault Rifle, Fieldhausen Arms was approached. Lighter than the standard LMG but considerably more powerful than an AR, the Fieldhausen Kampfkanone quickly became standard issue in most regular dragoon units. Some lighter units, like recon squads, still stick to the old Panzerknacker, though. The Kampfkanone may only be used by Dragoons, unless otherwise stated.
(KAMPFKANONE means something like "BATTLE CANNON" in english)
KAMPF= FIGHT,COMBAT,BATTLE
and
KANONE= BIG GUN,CANNON
