In what order may the vehicles proceed?

The correct order of vehicles proceeding as 1-3-2 can be understood by analyzing the general traffic and movement rules followed in military operations, which prioritize safety and tactical advantage.

In military convoys, the order of vehicles often depends on their size, capability, and the nature of the terrain or mission. Vehicle 1 may represent a lead or reconnaissance vehicle, which is optimal for leading the convoy and identifying potential hazards. Following this vehicle with 3—potentially a tactical support or armored vehicle—allows for immediate protection and response capabilities. The positioning of vehicle 2 at the end ensures that the convoy maintains a secure, organized profile while still being able to support as needed.

This sequence not only maintains the integrity and safety of the convoy but ensures effective communication and cohesion among the vehicles, maximizing operational effectiveness while minimizing risks. Understanding this strategic placement is crucial in military logistics and convoy operations.
