Greatest War Films: War films acknowledge the horror and heartbreak of war, letting the actual combat fighting or conflict (against nations or humankind) provide the primary plot or background for the action of the film. There are a significant number of influential, important, and milestone war films throughout cinematic history, outlined here.

Typical elements in the action-oriented war plots include POW camp experiences and escapes, historical recreations of major battles or war-related events, submarine warfare, spy or espionage tales, personal heroism, biopics of important war figures, "war is hell" brutalities, air dogfights, tough trench/infantry experiences, resistance movements, pre-war intrigue, veterans returning to the homeland, male-bonding buddy adventures during wartime - even black comedies about warfare. Themes explored in these war films include combat, survivor and escape stories, tales of gallant sacrifice and struggle, studies of the futility and inhumanity of battle, the effects of war on society, and intelligent and profound explorations of the moral and human issues.

In 2007, Military History Magazine created a special collector's edition highlighting their selection of the 100 Greatest War Movies, a critical guide to the best war films of all time, chronologically covering war films from Battleship Potemkin (1925) to Letters From Iwo Jima (2006), as this list does. The magazine wrote that "the movies that made the cut cover a full spectrum of life during wartime, were made by filmmakers around the globe and span the history of war from ancient days to now..." Almost all the films dealt with wars and battles of American involvement since the Civil War, and a vast majority of them dealt with World War II. Some of their films probably shouldn't have been on list: The Third Man (1949) for instance, was a political thriller rather than a war movie. Hitchcock's Notorious (1946), John Huston's The African Queen (1951) and The Man Who Would Be King (1975), John Ford's The Searchers (1956) and William Wyler's Ben-Hur (1959) were also not typical war movies. John Wayne's The Alamo (1960) was not a great film. Besides having ranking issues (ranking films of this sort seems to be a fruitless effort), the Military History magazine's list was a very comprehensive and detailed compilation.

A few films that were not in the Military History list (and included in this list, in part) were: The Birth of a Nation (1915), Intolerance (1916), Gone With the Wind (1939), The Great Dictator (1940), In Which We Serve (1942, UK), Destination Tokyo (1943), The Lost Patrol (1943), Back to Bataan (1944), The Fighting Sullivans (1944), Objective, Burma!
