Pulse Disruptors are stripped down versions of Protoss energy weapons reverse engineered from Immortals and Stalkers. In combat, they can lay down heavy firepower to quickly mow down enemy infantry with hundreds of high energy bolts. Each bolt is capable of burning a 5-8 inch hole through light and medium armor. More heavily armored and shielded targets will eventually be worn down by constant bombardment and heat build up. Pulse disruptors can even charge up a burst of energy to take down small to medium vehicles and airborne targets (Warhammer 40,000 - Space Marine: Plasma Cannon). The only drawback is that charged attacks require longer to cooldown from after use.
