Les Grau is a retired US Army officer who fought guerrillas in South Vietnam—and left on a stretcher. Consequently, his appreciation for guerrilla tactics came early in his career. The Army later taught him Russian, and his tours of duty included frequent trips to the Soviet Union and elsewhere. He has is the author of three books on the Soviet-Afghan War, including The Other Side of the Mountain: Mujahideen Tactics in the Soviet-Afghan War (with Ali Jalali). Mike (Misha) Gress grew up in the wilds of Siberia where everyone's dad, including his own, was a veteran of the fight against the Nazis. He joined the Soviet Army and served in the infantry (motorized rifle) forces, and afterward produced The Soviet-Afghan War: How a Superpower Fought and Lost with Les Grau.
