A standard Mark 1 Mauler of the Galactic Patrol with landing gear extended.
Galactic Patrol Maulers were slow, ungainly powerhouses of offense mounting the most powerful projectors ever placed on a mobile platform. Maulers were designed for one purpose only. To lock onto Boskonian raiders and destroy them by shear brute force!
Because of their slow speed Maulers were teamed with flotillas of Corvettes and Cruiser that would chase down and lock onto Boskonian ships with tractor beams and then go inert. The Mauler then would lumber into range to smash the villainous minions of Boskon into their component atoms.
Maulers possessed virtually unbreakable tractor beams, jammers to prevent enemy ships from drawing power from their cosmic energy screens. Armed with Macro and Primary Beams that could tear through the wall shields of the heaviest Boskonian SuperDreadnaught. A Mauler’s extremely heavy shielding protected it from anything any lesser vessel could throw.
Nothing less then a Solar Powered Sun Beam or Dirigible Planet could compare to the stupendous offensive power of a Mauler.
