What is the proper courtesy when it is necessary to pass an officer while walking?

When encountering an officer while walking, it is proper protocol to salute and request "by your leave Sir/Ma'am." This action demonstrates respect for their position and authority within the military hierarchy. The salute is a recognized military gesture that signifies acknowledgment and respect between personnel of different ranks. By asking for "leave," you are politely requesting permission to pass, which shows both deference and respect for the officer's status.

This practice is part of ingraining military courtesies, which are essential to maintaining order and discipline within the ranks. Such courtesies help foster a professional environment and indicate that you are aware of the customs and traditions inherent to military service. Adhering to this formality reinforces the respect for rank and responsibility that is fundamental to military operation and morale.
