intense gunbattle between Russians and Chechens

A group lied in ambush on the road of Russian armoured vehicles and tanks going forward to Argun and Grozny. They blew up the military vehicles before the intensive exchanging fire.
In the shots, the guerillas firstly deployed at the supreme points in the ambush site and made last preparations according to the plan. One of their vehicles was parked at the road, which had been furnished with remote control-explosions. All vehicles had to pass in low speed trough the way because of parked car. And then, there was a big boom exactly at the moment when Russian military vehicles were passing on the way. Finally- amid sounds of "Allahuekber"- a severe gun battle broke out between survived soldiers and Chechens.
By hit-and-run strikes at different 4-5 points, the fighters can damage the Russian troops heavily. As for Russians, they prefer to use sharpshooters and MI-24 helicopters in order to cope with the resisters.
