In northern Syria and neighboring regions of Iraq, the Kurdish People’s Protection Unit—or YPG—has modified vans, trucks and construction equipment with guns and shielding.

Which doesn’t mean the improvised tanks can shoot worth a damn … or survive a hit by the militants’ rocket-propelled grenades.

The DIY tanks are worse than useless on the battlefield—they’re a waste of time and effort and are likely to get their crews killed. But they sure do look cool—or hilarious, at least—on Twitter.

Some of the tanks function as ambulances, trundling through enemy fire to retrieve wounded Kurdish fighters, according to Opsiyon Haber, a Turkish news Website covering Kurdistan.

The DIY designs vary, as do their color schemes. The Kurds like to spray-paint their homemade tanks in gaudy “camouflage” and add eyes, flames and other features as flair. You might also see the improvised armored vehicles sporting YPG insignia and flags.
