Under which condition would Convoy Security be chosen instead of Route Security?

• A. When you have enough forces to secure the entire route
• B. When you don't have enough forces to secure the entire route
• C. When the route is short
• D. When the convoy is traveling at night

Answer: (B)

The main idea is choosing the security approach based on available forces. Convoy Security is used when you can’t cover every point along the route because there aren’t enough troops. In that case you protect the moving convoy as a unit, concentrating your security around it as it travels rather than trying to secure every segment of the route. If you have enough forces to secure the entire route, Route Security is the better approach, protecting each segment rather than just the convoy.

So the condition for choosing Convoy Security is not having enough forces to secure the entire route. The other options don’t fit because having sufficient forces would mean Route Security, and the length of the route or traveling at night doesn’t by itself dictate the method—the deciding factor is force availability.
