The surprising firepower unleashed by the Rust Grinders fully showcased why the Big Two imposed so many limitations on ship bunkers and artillery mechs.
With a little bit of jury-rigging and a dose of ingenuity, a crew of pirate technicians, engineers and perhaps a low-ranking mech designer or two were able to turn the flagship of the Rust Grinders into a warship!
Certainly, compared to affixing massive turrets and weapon mounts onto proper warships, mounting a ranged mech into a bunker didn't sound very impressive.
However, the crucial advantage of this method was that it was very simple! The pirates didn't need to enlist the services of a high-ranking mech designer or a CFA engineer.
