First of several new releases coming from GZG shortly are these Remote Wheeled Mini-Bots. Variants include MG, Rocket and Sensors/Recon.
They are lovely little models. Jon is also in the middle of creating tracked variants too. Despite the fact they are labelled 15mm, there is no reason why they can't be used for 28mm Modern and Sci Fi games as well. If you've played FRONTLINES: Fuels of War on the XBOX360 - you know how useful these little beasties can be!
