If units came upon a suspicious looking object, they could check it out with the MARCBOT. It would save time for the Explosive Ordnance Disposal teams, because they wouldn't have to come out to confirm or deny the object. The MARCBOT could do that,
I can definitely see these robots having a much more instrumental role in this and the following years than they did at the beginning of the conflict, due to the fact that a lot of the improvised explosive devices are on the small secondary streets,
