What is the primary purpose of controlling avenues of approach in movement and defense planning?

• A. To shape movement and provide protection
• B. To design supply routes only
• C. To determine vehicle color
• D. To set radio frequencies

Answer: (A)

The main idea is to shape how forces move and how the enemy can move, using the terrain and routes to create secure, predictable avenues for operation. By controlling these routes, you guide friendly movement along safer, more controllable paths while forcing or funneling the enemy into sectors where you have the advantage—allowing you to apply protective fires, maintain unit cohesion, and reduce the risk of surprise or flank attacks. In movement planning, this helps pick viable routes and align supports and defenses; in defense, it channels the assault into prepared sectors where you’re strongest. It’s not about supply routes alone, vehicle color, or radio frequencies, which don’t address protection or battlefield shaping.
