Food... The Mongolians had the best camp food. They set up a camp, started a fire and grilled mass amounts of meat over the fire. He claimed they were world class grillers.
Fighting style... Part of the time, my buddy was based out of Kabul. Taliban had frequent small scale but violent attacks on government and civilian targets. Coalition forces were based in fortified combat posts scattered in the city.
When there was a Taliban raid, according to my buddy, Americans and western forces in general would go by a playbook in their response. This was along the line of gather intelligence, assemble a reaction force and transport, drive to the fighting, deploy per plan and the fighting was largely over with by the time their overwhelming force was in position. Now though, the Mongols would leave the camp fire, grab their AKs and run to the sound of the guns. They wanted to get in on the fighting and did.
Very cool.
