Thank you. I'll briefly respond to that.
Just as a point of clarification, we don't need any vehicles that are a metre thick. We use technology to beat the rocket-propelled grenade threat.
The ability to pick up our personnel and equipment by helicopter and move them to a forward-operating base, instead of traversing the routes, is hugely important. That includes rations and spare parts and so on. We continually have to move personnel on those convoys for rotation, for rest, for medical purposes, and so on. The helicopters, we believe, both a chartered solution initially, and a Chinook solution, will reduce the risk to our soldiers significantly.
