15mm (1/100) scale Leviathan accessory weapon arm was designed to be used with the fast swap arm option for both the (15mm) Leviathan Crusader and Leviathan Mortis and all other variants that share the same chassis.

Not all close combat weapons are designed for anti-armor, the Ripper saw and Mauler claw are anti-fortification weapons.

The Mauler is used as a huge battering ram, its neo-muscle knuckles slamming forward with more kinetic energy than most artillery can muster, It also has the advantage of being a true appendage, able to tear the turret assembly from a tank or wrestle a Leviathan to the ground.
