What gun killed the most in WW1?

The Deadliest Firepower of the Great War

When the industrial scale of World War I collided with twentieth-century military tactics, infantry combat was completely redefined. Among the vast inventory of destructive armaments introduced during the conflict, none left a bloodier legacy than Germany's standard heavy machine gun, the Maxim MG 08.

Derived directly from Hiram Maxim’s pioneering 1884 design, the MG 08 became the cornerstone of defensive trench warfare. It was capable of pumping out an average of 500 rounds per minute over devastating distances exceeding 2,000 yards. Because it relied on a water-cooled jacket surrounding the barrel, crews could maintain continuous, suppressive fire for hours without risking a catastrophic meltdown.

Positioned cleverly across no-man's-land behind barbed wire networks, these weapons turned open-field charges into absolute devastation. The sheer mechanical efficiency of the MG 08 fundamentally shifted the balance of power on the battlefield, making traditional mass infantry charges obsolete and cementing a tragic new standard for military casualties.
