What essential information is required for convoy security planning?

The essential information required for convoy security planning includes the time and place of linkup, as well as the vehicle maintenance situation. Knowing the time and place of linkup is crucial for coordination among units and ensuring that all convoy elements can communicate and operate effectively together. This helps in synchronizing movements and ensuring that security measures are in place whenever the convoy halts or changes direction.

Additionally, understanding the vehicle maintenance situation is vital because it determines the operational readiness of the convoy. If vehicles are not maintained adequately, they could breakdown, making the convoy vulnerable to attack or ambush. Therefore, both the timing and logistical readiness of the vehicles directly impact the effectiveness and safety of the convoy operation, making this information paramount for proper planning and execution of convoy security.

The other options, while containing useful information, do not address the immediate and practical aspects of convoy security planning as directly as the time, place, and maintenance of vehicles. For instance, while weather conditions can influence the movement and visibility during a convoy, they do not provide the immediate tactical considerations needed for the convoy's integrity. Historical enemy tactics may inform broader strategy but are not as critical to the specific planning of a current convoy operation. Lastly, logistical support and communication frequencies contribute to operational success but
