About a 2 years ago I bought a copy of Tom Clancy's The Cardinal of the Kremlin, which revolves around the story of an American mole high up the Soviet chain of command (I won't spoil it for those who have not read it). But that is beside the point, a good chunk of the book was devoted to the Soviet war in Afghanistan.
In Chapter 17, the main Afghan character, The Archer (so named because of his use of Stinger SAMs) leads an attack on a Soviet battalion at it's base. At about the time the unit was eating lunch, the CO was the first to get killed. In Chapter 3 a Afghan sergeant attempeted to kill a Soviet captain and an Afghan LT loyal to the Soviets, just prior to an attack by the Muj.
Clancy is generally a good read, and is generally solid on the technical end of things, but here he not only told what was happening to the Soviet in A-Stan, he also told us what would happen when if we ever went in to A-Stan. A warning we would have been wise to heed.
