The DRG-SDW, christened 'Sidewinder" is a heavily customized 60 ton battlemech featuring an XL engine and support for MASC, giving it a speed over over 120 km/h. The main weapon is an AC20 class repeating autocannon that fires absolutely massive HESH shells at roughly 90-100 RPM, supported by a 6-tube SRM launcher. I have, however, removed those launchers to provide it with a pair of medium classified Pulse Lasers and improve the armor coverage.

If I charitably hold comparable the most modern enhancements of the Abrams MBT to tanks of the Inner Sphere in 3026, the Abrams may survive a single direct hit by the AC20, but will not survive the second shot and may succumb to the secondary weapons. Especially accurate return fire to the DRG-SDW's cockpit may smash into the protective plating, but barring a catastrophic failure it will hold with at least 65 to 75% integrity.

An ambush of at least three to six tanks may pose a much more credible threat and would need to be approached far more carefully, as the destructive power of the MBT's cannon (best estimated as a 'Medium Rifle' classification) could penetrate armor in a few accurate volleys and cause an ammunition explosion or decimate the cockpit.
