How is the hand and arm signal for Attention performed?

The hand and arm signal for Attention is performed by extending the arm sideways and waving it to the head. This action is a clear and universally recognized signal intended to catch the attention of personnel and convey readiness or alertness. The use of the arm extended sideways allows for visibility from a distance, ensuring that the signal can be seen by others in the vicinity. This specific gesture enables effective communication in situations where verbal commands might not be practical or possible, such as during noisy environments or when distance separates individuals.

The other techniques mentioned do not accurately represent the designated signal for Attention. For example, raising both arms above the head may convey a different message, possibly indicating a surrender or an expression of joy rather than alertness. Similarly, extending an arm forward or sideways with a specific palm orientation does not align with the standard established signal for calling attention, which emphasizes the waving motion towards the head.
