Tank From Outter Space

Looks like the end of a tank car set on top of it.

Captain Kirk called; He wants his tank back.

It's a Whambamulator 69. The lights flash when it shrinks to the size that it fits on the head of a pin and then they take it to somebody and unload it under their nose and then the crew goes and mines for gold. Then the lights flash when the Whambamulator 69 resizes to full size and the unload the cargo. Alien spaceships use the cargo to power their spaceships, like the Enterprise and di-lithium crystals.
It's on the internet so it's got to be true.

Definantly has a Marvin the Martian look. Where does the p31 space modulator go?

My guess is remote controlled. If something goes wrong, the red and blue lights flash, and everybody runs until the thing runs out of fuel..........

As some have speculated it looks like a remote control test bed or a remote target tug; BUT most times they have a cable and winch setup; more reliable and allot cheaper.
I know in the 80's and even today they still are developing remote sentries. Might explain the red and blue lights.
I saw one like a small turret-less tank running around in the no man's land between the fences following a buried wired.
The most scary thing about it it was armed with m60's and IF you were in that area and didn't have the correct RFID badge it would shoot you..
S.Korea is now fielding a "autonomous" armed robotic sentry now with live video feed back to the operator..

It is a non lethal, all terrain, beer recovery vehicle. Including flashing lights for emergency beer response!!

QM41 remote controlled target. Converted from M41.
