The ZSU23-4 had a partner

I don't think I mentioned the other vehicle that was parked beside the ZSU23-4.

It is amphibious (there were propeller housings and thrust diverters on the rear), it has six pneumatic tires, and a radar or two or more on top. It looked like the kind of vehicle that would travel with a pack of ZSU23-4's, to provide search radar and direct the fire of all of those 23mm cannon.

Here's a look at the front, with buddy Doug. I had to crank the brightness and contrast to compensate for bad hangar lighting.

Can anybody put a name to this unit?
