From one of today's New York Times stories (2/16/10) about the NATO/U.S. campaign in Marja, Afghanistan (emphasis added):
The heavy civilian toll highlighted the stressful and confusing nature of the fighting, especially in Marja, and of the difficulties inherent in conducting military operations in a guerrilla war, where insurgents can hide easily among the population.
Still, the deaths are troubling to the American and NATO commanders, who have made protecting civilians the overriding objective of their campaign–even when doing so comes at the expense of letting insurgents get away. The stream of news releases flowing from NATO headquarters detailing the episodes is testament to how seriously military commanders here take the problem.
Indeed, nothing demonstrates humanitarian concern more profoundly than numerous press releases.
