General Details
Name:  Improved Autocannon/20
Type (Category):  Weapon (Ballistic)
Technology:  Clan
Available To:  BattleMechs
Reference:  Interstellar Operations (p. 96)

Description:
Early Clan ballistic weapons tech also benefited from advanced metallurgy and construction techniques that rendered these classics of warfare lighter and more compact. These weapons enjoyed only a brief service life before more significant advances to the Ultra and LB-X autocannon types rendered standard-model cannons obsolete.

Game Rules:
All four improved standard autocannons perform in the same fashion, and with the same heat, damage, range, and to-hit modifiers as those made using the Inner Sphere technology base.

Construction Rules:
May be mounted on any available unit type in accordance with the unitís standard construction rules.
