Certainly. Let me start with your last question first.
We have engineers in theatre who are highly capable of ensuring our own mobility by dealing with unexploded ordnance, so the natures of explosives that have been cleared.... We also do this to help the local community, as individuals point and say, for example, we know there's a mine there, can you help us? Or these little wires sticking out of the ground look like an IED, or a leftover mortar bomb or an artillery round is lying in the open. This is something we can deal with quite easily. Those are the types of the explosives we have found on the ground.
