The Pnv-3 Siska Squad Cannon is a huge behemoth and a super-large equivalent of the recoil-less rifle. In fact, asking if the Siska is recoil-less would make any Helghast laugh. It fires anti-tank rounds with so much force that you don't feel the recoil because a servo-operated gyro-mount is required to keep you from becoming a literal human cannonball. It has six rounds of the powerful 66 mm high velocity explosive cartridges. Like the LS13 Shotgun, it can fire one or two rounds at time. However, the two round shots arc in a manner similar to that of the BLR-06 Hadra MRL, but they have less of an arc and a bigger spread pattern.
