When should a soldier salute while inside a building?

A soldier should salute while inside a building when reporting to their commander. This action is a sign of respect and adherence to military customs and courtesies. Saluting is not only a demonstration of respect for the rank of the commander but also signifies the soldier's acknowledgment of leadership and authority. The salute conveys discipline and professionalism, which are core values within military culture.

In contrast, saluting during physical training, while waiting for a briefing, or while participating in a discussion is not standard protocol. Physical training often involves movement and may not conducive to formal procedures like saluting, while the other scenarios may not necessitate such a formal acknowledgment of rank, particularly if the soldier is not in a direct reporting context. Thus, the context of reporting to a commander distinctly marks the appropriate time for saluting within a building.
