She pointed at the hulking length of the Huge artillery Cannon running the length of the 'Mech's spine, the barrel only a few feet above Aren's head, and wide enough to engulf his head totally. "This thing uses a Construction 'Mech's frame. the cannon is mounted on the crane's platform at the back, and each of the legs' pauldrons can drop and dig into the ground for stability when lifting a heavy load, or, in this case, sending ninety pounds of high explosives down-range."<br/><br/>She pointed at a small screen on the side of the cockpit wall, near the tape marks of the map she had up against that side. "Do a Size-weight comparison between your 'Mech, and mine. You'll find that Bipedal frames Can't even ~carry~ that gun, much less fire it, without severe internal damage due to the torque. So, having this thing carry a gun that No other unit can even ~think~ of mounting gives it reach, and punch, far beyond the normal area of engagement."
