Obviously, its just a generic battery operated tank toy, that shoots missiles and makes an engine sound. The generic toy came in several different colours. The UFO Missile tank came in orange, with a yellow turret and red missiles with an orange radar scanner.
My green and beige generic example, which I picked up at a Doncaster toy fair a few years back, cost me the princely sum of £1.50. On the box it's described as a Rocket Firing Tank. Everything worked, and it had four missiles, but the all important radar scanner was missing. However, that didn't prove a problem thanks to our own Bill Bulloch who supplied me with a spare one he had.
As a toy it looks pretty good and I suppose if you really stretched your imagination you could pretend it was one of the Moonbase Missile Launchers.
Here's a photo of the UFO Missile Tank box art showing a Moonbase Interceptor, Lunar Shuttle and a Shadair plane.There's also what looks like a Project SWORD Moon Crawler in the lower left hand corner.
This is the box that came with my generic example. Not quite as exciting I admit, but a lot cheaper.
