Utilizing taps on a helmet or a weapon is an example of what type of signal?

Taps on a helmet or a weapon are classified as a special signal because they convey specific, predetermined meanings to individuals within a military context. These signals are often used to communicate in situations where verbal communication may not be feasible or advisable, such as during covert operations or when silence is essential for operational security.

Special signals are distinct from auditory signals, which typically involve sounds like verbal commands or alerts, and visual signals, which refer to movements or gestures that are visible. Standard signals can refer to widely accepted procedures or methods, but taps on equipment have a unique context and specific implications known to those within a unit. The use of taps as a form of communication is designed to act swiftly and clearly without the need for additional context that standard or auditory signals might require.
