In many East Asian countries, The Art of War was part of the syllabus for potential candidates of military service examinations. Various translations are available. During the Sengoku period in Japan, a daimyō named Takeda Shingen (1521–1573) is said to have become almost invincible in all battles without relying on guns, because he studied The Art of War.[11] The book even gave him the inspiration for his famous battle standard "Fūrinkazan" (Wind, Forest, Fire and Mountain), meaning fast as the wind, silent as a forest, ferocious as fire and immovable as a mountain. The translator Samuel B. Griffith offers a chapter on "Sun Tzu and Mao Tse-Tung" where The Art of War is cited as influencing Mao's On Guerrilla Warfare, On the Protracted War and Strategic Problems of China's Revolutionary War, and includes Mao's quote: "We must not belittle the saying in the book of Sun Wu Tzu, the great military expert of ancient China, 'Know your enemy and know yourself and you can fight a thousand battles without disaster."[11] During the Vietnam War, some Vietcong officers studied The Art of War and reportedly could recite entire passages from memory.[citation needed] General Võ Nguyên Giáp successfully implemented tactics described in The Art of War during the Battle of Dien Bien Phu ending major French involvement in Indochina and leading to the accords which partitioned Vietnam into North and South. General Võ, later the main PVA military commander in the Vietnam War, was an avid student and practitioner of Sun Tzu's ideas.[12] America's defeat there, more than any other event, brought Sun Tzu to the attention of leaders of American military theory.[12][13][14] Finnish Field Marshal Mannerheim and general Aksel Airo were avid readers of Art of War. They both read it in French; Airo kept the French translation of the book on his bedside table in his quarters.[citation needed] The Department of the Army in the United States, through its Command and General Staff College, lists The Art of War as one example of a book that may be kept at a military unit's library.[15] The Art of War is listed on the Marine Corps Professional Reading Program (formerly known as the Commandant's Reading List). It is recommended reading for all United States Military Intelligence personnel and is required reading for all CIA officers.[16] According to some authors, the strategy of deception from The Art of War was studied and widely used by the KGB: "I will force the enemy to take our strength for weakness, and our weakness for strength, and thus will turn his strength into weakness".[17] The book is widely cited by KGB officers in charge of disinformation operations in Vladimir Volkoff's novel Le Montage.
