Which option is NOT a common vulnerability for combat convoys?

• A. Attacks on routes
• B. Great weather conditions
• C. Ambush risk
• D. IEDs

Answer: (B)

Vulnerabilities in combat convoys come from threats that enemies can exploit to stop, damage, or disrupt movement. Attacks on routes, ambush risk, and IEDs are classic hazards because they directly threaten the convoy’s safety and continuity, forcing slower progress, rerouting, or casualties.

Great weather conditions do not function as a vulnerability in the same way. They don’t create an exploitable opening for an adversary; instead they typically reduce some risks by improving visibility, navigation, and speed. Weather can influence operations, but it isn’t a vulnerability that enemies regularly leverage the way route attacks, ambushes, and IEDs are. So this choice is not a common vulnerability.
