What should be determined regarding vehicles for effective convoy security?

Determining the condition and maintenance of vehicles is crucial for effective convoy security because it directly impacts the reliability and operational capability of the convoy. Vehicles in optimal condition are less likely to experience breakdowns or failures during transport, which can pose significant risks to the security of the convoy and its personnel. Regular maintenance ensures that all mechanical systems are functional and that vehicles can perform as expected in various environments and under different conditions.

While knowing the types of supplies each vehicle carries, the size of the vehicle fleet, and the operating speeds of each vehicle are important factors for planning and operational readiness, they do not directly address the immediate need for operational reliability. Poor vehicle condition can compromise the entire convoy's mission, making maintenance a top priority for ensuring safe and effective operations.
