Karl Strecker was a German general during World War II who commanded several army corps on the Eastern Front. A career military and police professional, he fought in World War I and then served in the paramilitary Security Police of the Weimar Republic. Strecker welcomed the rise of Hitler and found favor with the regime, earning rapid promotions in the armed forces of Nazi Germany, the Wehrmacht. Strecker commanded the German Army's XI Army Corps in the Battle of Stalingrad and was the last German general to surrender his command in the city. He spent twelve years in Soviet captivity before being released in 1955.

Helmuth Groscurth was a German staff and Abwehr officer in the Wehrmacht and a member of the German resistance. As an intelligence officer he was an early proponent of the Brandenburgers, commanded unconventional warfare operations in the Sudetenland, and was an active conspirator against Hitler's agenda. He was later reassigned to the regular army following his criticism of war crimes committed by German forces in Poland. After commanding an infantry battalion in the invasion of France he assumed a variety of staff roles. He was involved in the events of the Bila Tserkva massacre where he attempted to avert the killing of Jewish children.
