The Praying Mantis was an experimental two man vehicle designed to approach obstacles and fire over them. Based on the Universal carrier, the two man crew were in the raisable central section (note the viewports). The vehicle was armed with two Bren guns in a single mount.
Here you can see the Universal Carrier running gear.
Here is the rear mounted engine.

This would make a perfect Automated Carrier for Konflict '47.
