Which color band may indicate the use of smoke in munitions?

A black band on munitions is commonly used to indicate that the ordnance contains smoke-producing materials. This color coding is important for safety and identification purposes, allowing both military and defense personnel to quickly recognize the type of munitions and their intended use. When a black band is present, it signifies that the munition is intended for signaling or screening purposes, utilizing smoke to obscure visibility or communicate.

The other color bands do not correspond to smoke munitions. For example, yellow bands typically denote high-explosives, red bands are often associated with incendiary or explosive rounds, and green bands may indicate practice or inert munitions. Understanding these color codes is crucial for identifying the purpose and function of various munitions in the field, ensuring proper handling and deployment.
