The UN has developed some tools. They have new guidelines for peacekeepers and operations. They're trying to get the contributing countries to apply and also to better train their soldiers. The missions, as defined in the Security Council resolutions, are better defined and provide for protection of civilians.
One example is Darfur. While it's not a good situation there, the presence of the African Union mission and the United Nations mission has made a difference in terms of the protection of civilians. It hasn't solved the situation, so it's not working in terms of resolving the problem, but the number of attacks on civilians in Darfur has significantly decreased, and that's because the mission is better equipped now.
Because of the nature of conflict, what you need has also changed. You don't necessarily need big trucks and tanks, as we had in the Balkans in the nineties. You need more mobility; you need helicopters so you can move quickly from one place to the other. The armoured vehicles and so on move in smaller teams.
So the way of operating has changed somewhat to make them more nimble and more adjusted to the requirements of the situation.
