The following is a list of German military equipment of World War II which includes artillery, vehicles and vessels.
 World War II was a global war that was under way by 1939 and ended in 1945.
 Following political instability build-up in Europe from 1930, the Germans, which aimed to dominate Europe, attacked Poland on 1 September 1939, marking the start of World War II.
 The war in Europe ended 8 May 1945 with capitulation of Germany to the Allied forces.
World War I (WWI or WW1), also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918.
 More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history.
 Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare.
 It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved.
 Unresolved rivalries still extant at the end of the conflict contributed to the start of the Second World War only twenty-one years later.
World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier.
 It involved the vast majority of the world's countries—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis.
 It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries.
 In a state of total war, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources.
The military history of Mexico consists of several millennia of armed conflicts within what is now that nation's territory and includes activities of the Mexican military in peacekeeping and combat related affairs worldwide.
 Wars between prehispanic peoples marked the beginning of Mexico's military history, the most notable of these fought in the form of a "flower war".
 After the Spanish conquest of Mexico in the 16th century, indigenous tribes were defeated by Spain, thus beginning a three century era of Spanish dominance.
 Mexico's struggle for independence began primarily in the 19th century, and was marked by internal conflict of early rulers after defeating the Spanish in 1821.
 The Mexican–American War in the mid 19th century ended in the defeat of Mexican forces, and the loss of two-fifths of the national territory.
 In the remainder of the 19th century, a series of conflicts began in Mexico, as the War of the Reform and the defeat of the French during their intervention in Mexico marked events in that era.
