German Army (Wehrmacht): The German Army (German: "Heer" , ] ) was the land forces component of the Wehrmacht, the regular German Armed Forces, from 1935 until it was demobilized and later dissolved in August 1946.  Though often erroneously restricted to the ground forces, the Wehrmacht also included the Kriegsmarine (Navy) and the Luftwaffe (Air Force).  During World War II, a total of about 13 million soldiers served in the German Army.  Most army personnel were conscripted.

Trasimene Line: The Trasimene Line (so-named for Lake Trasimene, the site of a major battle of the Second Punic War in 217 BCE) was a German defensive line during the Italian Campaign of World War II.  It was sometimes known as the Albert Line.  The German Commander-in-Chief (C-in-C), "Generalfeldmarschall" Albert Kesselring, used the line to delay the Allied northward advance in Italy in mid June 1944 to buy time to withdraw troops to the Gothic Line and finalise the preparation of its defenses.

Belgian Armed Forces: The Belgian Armed Forces (Dutch: "Defensie" ; French: "La Défense" ) is the national military of Belgium.  The Belgian Armed Forces was established after Belgium became independent in October 1830.  Since that time Belgian armed forces have fought in World War I, World War II, the Cold War (Korean War and army of occupation of the Federal Republic of Germany), Kosovo, Somalia and Afghanistan.  The ParaCommando Brigade intervened several times in Central-Africa, for maintaining public order and evacuation of Belgian citizens.  The Armed Forces comprise four branches: the Land Component, the Air Component, the Marine Component and the Medical Component.  It is currently active in Lebanon, Afghanistan, the Gulf of Aden and conducting anti-ISIS operations in Iraq.

Kurt Mälzer: Kurt Mälzer (2 August 1894 in Altenburg – 24 March 1952 in Werl) was a German general of the Luftwaffe and a war criminal during World War II.  In 1943, Mälzer was appointed the military commander of the city of Rome, subordinated to General Eberhard von Mackensen under the overall command of Field Marshal Albert Kesselring.  Under his authority, Mälzer commanded not only the garrison Wehrmacht troops in Rome itself, but also indirectly the SS security forces in the city (although these troops were nominally under the authority of the SS and Police Leader of the region, Wilhelm Harster).

Siegfried Westphal: Siegfried Westphal (18 March 1902 – 2 July 1982) was a German general in the Wehrmacht during World War II.

Thus, he recognized the cryptographic weaknesses of the Enigma rotor key machine used by the German armed forces to encrypt their secret communications.

War crimes of the Wehrmacht: War crimes of the "Wehrmacht" were those carried out by the German armed forces during World War II.  While the SS (in particular the "SS-Totenkopfverbände", "Einsatzgruppen" and Waffen-SS) of Nazi Germany was the organization most responsible for the genocidal killing of the Holocaust, the regular armed forces represented by the "Wehrmacht" committed war crimes of their own, particularly on the Eastern Front in the war against the Soviet Union.

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.

OB West: The German Army Command in the West ("Oberbefehlshaber West" (German: initials OB West) was the overall command of the Westheer, the German Armed Forces on the Western Front during World War II.
