Here is the UK MUTT
Its the Modular Universal Tactical Transport
Its the tactical arm of the British APC forces. Each APC is accompanied by an air drone and a MUTT. The MUTT provides a unique offensive arm and the drone provides live recon information. The APC provides guidance and support for the MUTT and the drone and can provide tactical artillery support.
The Mutt is about the size of a small car and can be used autonomously to the APC
Ill have some concept work of the APC up and ready soon :)
