Multi-laser
From Lexicanum
The Multi-laser is a variant of Lasgun technology. It boasts a high rate of fire with a good range and decent killing ability. Like its closer compatriot, the Lascannon, it uses huge, box-like power cells which cannot be recharged and must simply be thrown away after use.
They are mounted primarily on Sentinels and Chimeras, part of the Imperial Guard Structure, and due to the high manoeuvrability of the walker they can be quickly deployed where they will do the most damage. They are especially good at hunting low-armoured transports. Also, they are effective against horde armies with poor armour, such as Orks and other Imperial Guard forces.
While the standard Lascannon is a semi-automatic weapon (one squeeze of the trigger fires one shot), the Multi-laser is fully automatic - it fires multiple laser beams as long as the trigger is held down. The Multi-laser can be considered to be a bigger variant of the Hellgun.
The Eldar have a similar weapon called a Scatter Laser which has a better rate of fire and a similarly more Eldar-like design.
