Imagine you are in command of a troop operating in an area where neither you, nor any of your team has been before.
You are well briefed and aware of potential danger points where the enemy may lie in ambush...
There are alleyways to the side of the road concealing opponents, and snipers are hidden on rooftops, behind walls, in doorways - they could be anywhere.
Danger is all around and an improvised explosive device waits for you to approach.
You have a good intelligence picture gathered from multiple joint and coalition sources, including satellite information and manned and unmanned aircraft feeds.
But you know opposition forces were in the area recently and there is no way of knowing if they left, or if they are still there waiting to ambush you and your troops.
