Answer:
Trench warfare is a type of land warfare using occupied fighting lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare lasting for several years took place on the Western Front in World War I. Following that war, "trench warfare" became a byword for stalemate, attrition, sieges, and futility in conflict.[1]
Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage.[2] On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire. The area between opposing trench lines (known as "no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties.
With the development of armoured warfare and combined arms tactics, emphasis on trench warfare has declined, but it still occurs wherever battle lines become static.
