Chechen ambush
n.— «The insurgents had hoped to spring what is called a Chechen ambush. The strategy, Marines determined later, was to wound Marines attempting to enter the building. When other Marines came to help, an insurgent sniper down an alleyway was to pick off corpsmen, radio operators and officers. And when enough Marines or vehicles were gathered, the insurgents planned to fire rocket-propelled grenades.» —“In heat of battle, a hero emerges” by Tony Perry in Albuquerque, New Mexico SouthCoastToday.com (Massachusetts) Oct. 3, 2006.
