Which command is used to instruct troops to stand still at attention?

The command to instruct troops to stand still at attention is "Attention." This command is fundamental in military training and signifies that the soldiers should stand in a specific posture that conveys readiness and discipline. When given the command "Attention," troops align themselves to face forward, with their feet together, arms placed straight down at their sides, and eyes looking ahead. This is a crucial formation for maintaining order, discipline, and focus, especially during ceremonies and formations where presentation is significant.

Other commands mentioned serve different purposes. "Forward March" directs troops to move forward, while "Stand at Ease" allows for a more relaxed posture, indicating that soldiers can be less rigid but still require a degree of attention. "Parade Rest" further relaxes the stance, permitting soldiers to rest while still remaining in a state conducive to immediate response. Each of these commands has its specific context and intended use, highlighting the importance of understanding military commands and their meanings in training and operational scenarios.
