Lester W. Grau is a retired U.S. Army Lieutenant Colonel. He served as an infantry officer and a Soviet Foreign Area Officer (FAO) throughout his career. He fought in Vietnam. In 1981, he completed one year of Russian language training at the Defense Language Institute at Monterey, California and then graduated from the U.S. Army Russian Institute (USARI) in Garmisch-Partenkirchen, Germany in 1983. USARI was a two-year post-graduate school which dealt with all aspects of the then Soviet Union and all classes were taught in Russian. He has served in Moscow and traveled extensively in the former Warsaw Pact and former Soviet Union and continues that travel today. Since 1983, his work has exclusively been in the area of Russian and Soviet tactics and operations. As a combat infantryman, he finds it fascinating to compare and contrast how both the US and USSR fought and fight.
