Thank you.
Back to the safety question, again, as it relates to our men and women in uniform, I think all of us around this table are very much aware that a large majority of the deaths that have occurred, unfortunately, in Afghanistan have occurred because of IEDs and so on, as opposed to active combat. So whether we're looking at procuring a vehicle with metre-thick steel or medium-lift helicopters.... I'm wondering if maybe Mr. Williston, or one of you, could expand on how the procurement of medium-lift helicopters would in fact make huge strides in improving the safety of our men and women in uniform.
