Get raided by, you mean. Having military grade quality with armored design ethics, that'd be tanks, or rather shitty little MG tankettes, plural, or at least various brands of light AFV. More armored cars than tracked vehicles, presumably, although it's probable that the nutters have dredged up the Christie suspension so they can have both at the same time. 'A Fucking Tank' is an actual chart result for the flagship vehicle, so MBTs are a no go. Legendary Car in combination with the traits probably translates to a super-Hummer or a Stryker or something with a cramped scrap turret.

I'll be looking over the chart to make sure whatever extrapolations I make from the rolls don't fall into other explicitly defined roll groups, but I'm thinking filetoothed borderline muties turned bad-tempered punks turned paramilitarist weapon-fetishists hailing from the nuked out surroundings of an Aussie silo that botched its launch cycle (Australia explored developing a nuclear capability historically, but signed the NNPT and never went through with it, yet considering how the Mad Max timeline went, there's probably a divergence here) who're driving imitative cold war tech versions of Hobart's funnies in an ill-conceived military campaign after the founder of the band broke into a secondary bunker of the silo, still running on reserve power, and using a blueprinting program (or else one of the personnel' novelty programs/games and thinking it's a military grade blueprinting program) to properly balance out the vehicles. Seeing as they consist of outback muties who only know that everything went to shit when the nukes went off- one over their heads, even, although not a proper fusion detonation nor at ideal airburst height- after getting rallied by a bunch of scrappers high on military vernacular, they've got the idea of organizedly sticking it to 'the fuckers' responsible for Mad Max's post-nuclear, post-peak oil shitshow while holding the pretension of but not actually establishing a transitional government, nor actually understanding what a transitional government entails, or is, save that they read it in a manual on martial law and it's a thing they need to establish. 

This largely manifests in raiding the shit out of other raiders for being raiders, more prickly and insular settlers for holding onto surplus supplies that ought be redistributed (mostly to the column and whatever poor waste-lost sods they happen to pass by while the surplus lasts) or people who look at them a little too funny while the column is taking a pit stop and don't respond to the subsequent R. Lee Ermey treatment the right way as the muties peacock around. These habit produce a lot of fresh scrap, as does their home base/stomping ground, where the EMP of the nuke knocked out plenty of planes & motor vehicles as well as leaving lots of dead infrastructure to pull apart. And tesla coils draw their power off from some dubiously wired diesel-electric drives, since the engineers couldn't think of any better way to deal with the occasional overload. That's the very rough working concept, at least. The gears are turning.
