Who exits a vehicle first according to military protocol?

In military protocol, the officer of the highest rank exits the vehicle first. This practice is rooted in the hierarchical structure of the military, where rank and leadership are paramount. The senior officer leading the mission or unit demonstrates their authority and responsibility by being the first to exit, ensuring they establish visibility and situational awareness upon leaving the vehicle.

This protocol fosters discipline and order within the ranks, as it reminds all personnel of the established chain of command. It also serves practical purposes; by allowing the senior officer to be the first one out, they can assess the environment and provide guidance to others following after them.

The other options do not align with this established protocol. The lowest rank would not exit first as that could create confusion and undermine the chain of command. The driver does not necessarily exit first because their primary responsibility is to secure the vehicle and facilitate the movement of the senior personnel. Lastly, the last person to enter exiting first may create disarray, disrupting the overall order established in military operations.
