A dozen more guns roared out on the right flank, lighter guns firing loads of musket balls.

Firing loads are transmitted to the ground through this tripod, isolating the hydraulic cylinders of the platform, which provides for greater reliability.

The radial arrangement of locking lugs distributes the firing load evenly around the bolt head and barrel socket, reducing stress and increasing the longevity of these critical components.

Also obeyed is the Corollary of the Ruthless But Stupid Villain: bad guys chase and often catch up with Neeson's car, firing loads of ammo, but never think to shoot out one of its tires.

Its modern Target Acquisition Devices together with a specially designed Recoiling Mortar System, attenuates the firing loads and enables mounting the systems on wheeled and tracked AFV's, or even soft-skinned vehicles such as trucks.
