Copy from Wikipedia:
"In January 2001, the Ka-50 saw its first combat operation, as it fired on enemy positions in Chechnya. Later, it would undertake several missions inside that war zone, although not as much as the more numerous Mil Mi-24 perhaps better suited to the more guerrilla-type warfare there." :smilewink:
