USA HISTORY

Detailed explanation-1: -World War I popularized the use of the machine gun-capable of bringing down row after row of soldiers from a distance on the battlefield. This weapon, along with barbed wire and mines, made movement across open land both difficult and dangerous. Thus trench warfare was born.

Detailed explanation-2: -Early land warfare tactics included the use of cover, charges and counterattacks. Land battles quickly led to trench warfare on the Western Front in Belgium and France. Each side occupied fighting lines (fronts) made up of trenches dug into the ground or breastworks constructed above low-lying country.

Detailed explanation-3: -What is trench warfare? Trench warfare is a type of combat in which the opposing sides attack, counterattack, and defend from relatively permanent systems of trenches dug into the ground.

Detailed explanation-4: -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.
