My father, John Sadlak was in WW2. He was in the 2nd armored division, 67th armored regiment, 3rd battalion, G company. His separation papers list his battles and campaigns as Tunisia, Sicily, Normandy, Northern France, Rhineland, Ardennes, and Central Europe. He was a tank driver, medium 2736. I am beginning to write his involvement in WW2, and would appreciate any information.
