Albert Kesselring Albert Kesselring (30 November 1885 – 16 July 1960) was a German "Luftwaffe Generalfeldmarschall" during World War II. In a military career that spanned both World Wars, Kesselring became one of Nazi Germany's most skilful commanders, and one of the most highly decorated, being one of 27 soldiers awarded the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds. Nicknamed "Smiling Albert" by the Allies and "Uncle Albert" by his troops, he was one of the most popular generals of World War II with the rank and file.
Panzer ace "Panzer ace" ("tank ace") is a contemporary term used in English-speaking popular culture to describe highly-decorated German tank ("Panzer") commanders and crews during World War II. While not prevalent in World War II within the Wehrmacht, it was at times used by the Waffen-SS to publicise its most successful personnel, as the SS organisation was far more attuned to the propaganda imperatives of Nazi Germany. These commanders were credited with the destruction of large numbers of tanks and other armoured vehicles. The British and United States militaries did not recognise any of their tank commanders for "tank kills" or publicise their achievements, though some were also responsible for destroying a large number of enemy tanks.
