 Given that almost certainly both sides have tended to exaggerate enemy military casualties while minimizing their own and grossly underestimating its responsibility for civilian losses, the Russian-Chechen Friendship Society set the conservative estimate of death toll in this time period at about 150,000 - 200,000 civilians, 20,000 to 40,000 Russian soldiers, and possibly the same number of Chechen rebels.In February 2003, the Union of the Committees of Soldiers' Mothers of Russia, estimated that some 11,000 servicemen have been killed, with another 25,000 wounded, since 1999.It also estimated the civilian death toll at about 20,000 people.
