What color and markings identify WP mortar rounds?

WP mortar rounds, which contain White Phosphorus, are identified by a specific color coding that aids in the quick identification of the type of round. The correct identification is light green with red markings. This distinct coloring serves not only to differentiate WP rounds from other types of munitions but also to alert personnel to the hazardous nature of the contents. White phosphorus is used for its incendiary properties and to create smoke, so being able to quickly recognize these rounds is crucial for safety and operational effectiveness in the field. The combination of light green and red is standardized across military training to ensure that soldiers can readily spot and handle this type of munition without confusion.
