In addition to the "big iron" being used in RIMPAC exercises, there are examples of "little iron" robots being field tested to protect and support the ground forces. I got a chance to see a couple of them this past weekend. Shown in the photo is the Modular Advanced Armed Robotic System (MAARS) unit manufactured by Qinetiq. This system packs a M240B medium machine gun along with a spotting scope, an infrared scope and viewing cameras for a 360 degree field of view. The model I saw demonstrated did not have a gun mounted to it. The unit also has rubberized tractor treads making it suitable for rocky terrain. Field engineer Rich Leemon did tell me that it wasn't all-terrain. The MAARS robot is best suited for unpaved rural roads. MAARS is operated by remote control from a suitcase system or from a wearable controller, as modeled here by Jasmine Guevara, PACOM public affairs. The Bellows Marine Corp Training Area where the exercise took place was made up to appear like an Afghani village. You can see the flag on the building and the men in the foreground behind MAARS are role players brought in from San Francisco. Evaluators of the MAARS looked for system vulnerabilities and operational effectiveness by Marines controlling the units in a free play exercise. The MAARS units run about $350K each and are still in the evaluation stage. In this video Rich Leemon explains the general operations of the MAARS as he guides it back onto the truck. Next up is GUSS.
