The CENTURY 21 MOBILE BRIDGE AND COMBAT TANK is one of the less common C21 offerings. Like the Hurdler it is a straight military vehicle but it wouldn't look out of place in a SWORD fleet I don't think. I've never seen this toy in the 'flesh', the above picture of an incomplete example is courtesy of Ebay from a couple of years ago. And like the Hurdler it has its doppelganger (or origin?) by MARX in the shape of the CAP FIRING TANK and more closely the SPACE TANK pictured below, which even has the same red barrel tip shown on the box art. Odd that Century 21 didn't opt for a space theme rather than military. I do love this C21 toy though and can't wait to actually see it one day!
