The signs are everywhere: chem trails in the sky, aliens are probing people, and the world is coming to an end soon. Or at least that’s what those people holding up signs on the corner say. But if this recent auction in Portola Valley, California, was any indication, when life as we know it ends, there will still be some things left for an epic tank battle.

All joking aside, the event owed its inception to a certain Jacques Littlefield, founder of the Military Vehicle Technology Foundation and avid collector of all things treaded and bound for the battlefield. Littlefield, who died in 2009, donated his collection to the Collings Foundation, a nonprofit organization devoted to “preserving the machines that helped build the world and helped keep it free.” The organization kept 80 of the vehicles for itself, and let the rest–some 350 pieces–go toward the auction.

Let’s rattle through a few of these steel beasts, shall we? First up, we have Lot #5004, a genuine Pz.Kpfw. IV from Germany.

Sporting a 75mm cannon, 88mm-thick steel armor on the turret, and a 296-horsepower Maybach V12, this battleship-gray specimen reportedly bears the marks of usage from three different countries, including Czechoslovakia, Syria, and Israel. Although this giant didn’t make the cut (one of only five lots) at the auction, that can only mean good things for the rest of us looking to buy a legitimate tank.

Next, we have this rather imposing relic from the Cold War. You may remember seeing or hearing about these thing during the Persian Gulf War: SCUD missile launchers. In this case, it’s an 8K11.

Rest assured, the buyer that plopped down $300K for this treaded terror is in no way a threat to major metropolitan areas. The missile is simply a prop, but it’ll definitely do the trick at the new owner’s next house party.

Several more of these awesome machines were sold to high-rolling auction guests hailing from 37 states and 10 different countries, and it wasn’t a bad haul for the Collings Foundation, which netted over $10,000,000 in sales. Now, where can we find those five tanks that didn’t sell…
