From First Strike Mod Wiki
One of the most powerful repeating blasters in the Imperial arsenal, the E-WEB Heavy Repeating Blaster requires an external generator carried by a Support trooper to fire more than a few shots. Once deployed the E-WEB is able to lay down almost continuous suppressive fire on enemy positions. Be warned, though, that the weapon has a tendency to topple if you don't keep your aim level with the horizon while deploying it. It is also recommended that you only deploy it on level ground.
