Which of the following describes how vehicles are dispatched in an infiltration convoy movement?

Infiltration convoy movements are characterized by a need for stealth and the ability to maneuver through potentially hostile environments while avoiding detection. The correct choice describes the method of dispatching vehicles as occurring individually or in small groups at irregular intervals. This approach helps minimize the risk of enemy detection and allows for greater flexibility in responding to threats.

By using this strategy, convoy units can spread out, reducing the chance of a coordinated attack by any adversaries. Vehicles moving in smaller formations can also take advantage of natural cover and concealment, making them less conspicuous. This method is essential for maintaining operational security and enhancing survivability in a combat scenario, where the element of surprise and discretion plays a critical role.

The other choices suggest more organized or simultaneous movement patterns, which do not align with the principles of infiltration. An organized formation or groups at scheduled intervals could easily attract attention and compromise the mission. Dispatching all vehicles at once in a single line would be highly vulnerable to detection and attack. Therefore, the individual or small group dispatch method at irregular intervals is the most effective tactic in an infiltration context.
