'Mechs can be equipped with a variety of external heavy equipment. Though some of this equipment is tailor-made to inflict damage - such as a hatchet or sword - most such equipment has other uses. However, the agility and strength of 'Mechs means that they can use any such equipment in a physical weapon attack against a potential target As with all physical attacks, the base to-hit number is equal to the MechWarrior’s Piloting Skill Level.
The Physical Weapon Attacks Table below shows all the various equipment that 'Mechs can use to make a physical weapon attack, along with relevant information such as to-hit modifiers, Damage Value, the To-Hit Location Table to be used and so on.

Critical Hits: Like weapons, a critical hit to any slot for any equipment shown on the table below destroys the equipment, rendering it useless for the rest of the game.
