Answer :
Final answer:
The machine gun is widely regarded as the most deadly weapon of World War I due to its role in causing high casualty rates, particularly during significant battles. While other weapons like tanks and chemical weapons also contributed to the conflict's lethality, machine guns had the most immediate and devastating impact on troop casualties. Their effectiveness in defending positions against larger forces marked a significant change in warfare tactics.
Explanation:
Most Deadly Weapon of WWI
During World War I, multiple weapons contributed significantly to the high casualty rates; however, the machine gun is often considered the most deadly weapon. Machine guns changed the dynamics of warfare, allowing small numbers of soldiers to defend positions against much larger forces effectively. For example, during the Battle of the Somme in 1916, machine guns caused an estimated 60,000 British casualties on the first day alone.
While tanks and flamethrowers were introduced during the war, their impact was not as immediate or widespread. Chemical weapons, although lethal, such as chlorine and mustard gas, were used primarily to demoralize and incapacitate troops rather than to kill en masse in the same way machine guns did. Therefore, while all these weapons had deadly effects, the machine gun's ability to inflict mass casualties quickly on the battlefield makes it the most infamous weapon of World War I.
