Which term refers to delaying or stopping the enemy by obstructing their movement?

• A. Block
• B. Contain
• C. Canalize
• D. Reconnaissance

Answer: (A)

Delaying or stopping the enemy by obstructing their movement is blocking. The idea is to place obstacles or barriers that physically hinder forward progress, disrupting their plan and buying time for your forces. This focuses on stopping or slowing movement along paths or routes the enemy would use. Canalize, by contrast, means to channel or funnel the enemy into specific routes, which concentrates their movement rather than simply stopping it. Contain implies keeping the enemy within a defined area to prevent broader exploitation, not specifically obstructing a route. Reconnaissance is about gathering information on enemy activity, not hindering movement. So blocking is the best fit for obstructing and delaying the enemy’s movement.
