To prohibit or seize enemy movement through a zone is to

• A. Interdict
• B. Destroy
• C. Exfiltrate
• D. Isolate

Answer: (A)

Blocking enemy movement through a zone is interdiction. Interdiction focuses on denying, delaying, or disrupting the foe’s ability to move along routes, through a zone, or between areas—using fires, obstacles, and other means to make passage difficult or impossible. The objective isn’t necessarily to destroy every asset, but to obstruct mobility so the enemy cannot maneuver effectively.

The other terms describe different aims: destroying targets is about physically eliminating assets, rather than specifically preventing movement through a designated area; exfiltrating means pulling people or forces out of an area; isolating refers to separating or cutting off an area or unit from support, which is a containment concept rather than specifically prohibiting movement through a zone. Hence, interdiction best fits the description.
