What distinguishes the coloration of FRTR mortar rounds?

The coloration of FRTR (Fire Resistant Tactical Round) mortar rounds is characterized by blue and white markings. These markings are specifically applied to signify that the round is designated for particular tactical use, differentiating it from other types of munitions. The blue color typically indicates a training or practice round, while the white markings can denote specific features or a special purpose. This color coding helps soldiers quickly identify the type of round being used in the field, which is crucial for ensuring the proper deployment and safety during operations. Recognizing these markings allows personnel to manage ammunition effectively and adhere to operational standards.
