Which type of explosive is classified as 'military grade'?

C4 is classified as 'military grade' because it is a specifically formulated plastic explosive that is widely used by military and special operations forces due to its stability, effectiveness, and versatility. Unlike other explosives that may be used in various civilian or industrial applications, C4 is designed and manufactured under strict military standards, ensuring a high level of safety and performance in tactical scenarios. Its composition includes a polymer that makes it easy to mold, allowing for a range of uses from demolitions to breaching operations.

In contrast, while blasting gelatin, dynamite, and potassium nitrate have explosive properties, they do not meet the same military specifications or intended applications as C4. Blasting gelatin is often used in civil engineering, dynamite has historical significance but is less commonly used in military operations today, and potassium nitrate primarily serves as an oxidizer in various applications rather than a primary explosive for military use.
