Question

Quizplus · Accepted Answer

Artillery and machine guns were the primary weapons used in World War I that forced soldiers to take cover in trenches to avoid being hit by the deadly barrage of bullets and shells. While poison gas and tanks were also used during the war, they did not have as significant an impact on the development of trench warfare as the constant barrage of firepower from the enemy's artillery and machine guns. Airplanes were used for reconnaissance and bombing, but did not have a direct impact on trench warfare.
