M3 & M5 Stuart light tank 1940-1945, 1999:p. 3 (M3 and M5 family of light tanks; Stuart family) p. 8 (confusing similarity in nomenclature, the M3 light tank and M3 medium tank. The M3 light tank was called the General Stuart, and the M3 medium tank was named the General Lee ... None of these names were sanctioned by the US Army, nor were they commonly used by US troops during the war. However, the names did become popular in the United States after the war, and are still widely used)
