What is typically found on the casing of bombs to indicate the type and purpose of the munition?

The type and purpose of a munition are typically indicated by color bands on the casing of bombs. These color bands provide visual information to munitions handlers about the bomb's capabilities, intended use, and type of explosive contained within. For instance, a specific color may denote whether the bomb is high-explosive, training, or incendiary, allowing personnel to quickly identify the munition's role on the battlefield or during training exercises.

While warning labels, serial numbers, and manufacturer's markings serve important purposes—such as safety information, inventory tracking, and identifying the supplier or manufacturer—they do not communicate the specific type and intended use of the munition as effectively as color bands do. Thus, color bands are a critical feature on bomb casings for clear and immediate understanding of a munition's characteristics.
