What category does M314 fall under?

M314 is categorized as an illumination round, which is used to provide light over a designated area during night operations. This type of round is essential for enhancing visibility on the battlefield, allowing troops to see their surroundings and engage effectively during darkness. The M314 functions by bursting in the air and producing a bright light, illuminating the area below, which is crucial for maneuvers, observation, and targeting. Its primary purpose is to aid in tactical operations rather than delivering explosive power or creating cover through smoke.
