You're always concerned about any weapon system, but as soon as you hear about MANPADS, it becomes a new level of concern. We had this threat in Afghanistan and we always—going back to the question about intelligence—tried to gain an understanding of how many of these systems were in the country and whether they had used them. Understanding the pattern of use is important because it's always a threat and you have to take everything into account.
Understanding the human geography, you see that these are status symbols. Somebody who walks around with one of these things is a pretty important guy. Once you fire, it's gone. You want to walk around with it, but you use it and it's gone. Going back to understanding the culture, you need to know how they view these things, and that can help mitigate some of that risk. It's a concern that we should all be cognizant of.
