Which military tactic involves armies digging trenches and fighting from them?

• A. Trench Warfare
• B. Turning Point
• C. Urbanization
• D. USS Maine

Answer: (A)

This question tests trench warfare, a military tactic in which armies dig long trenches and fight from them. The trench system protects troops from enemy fire and creates fortified positions from which attacks and counterattacks occur across no-man’s-land, often resulting in prolonged stalemates. The description fits exactly: soldiers living and fighting from dug-in positions rather than out in the open. The other options aren’t tactics: a turning point is a pivotal moment in a conflict, urbanization refers to the growth of cities, and USS Maine is a ship associated with a historical incident, not a fighting method. Trench warfare became infamous during World War I as front lines stretched into extensive networks of trenches.
