Which ammunition type is commonly used in tactical operations for rapid-fire scenarios?

High-explosive rounds are specifically designed for tactical operations where rapid-fire capability is essential. These rounds deliver a significant amount of explosive force upon impact, allowing for effective engagement of enemy positions or vehicles. They can create substantial damage over a wide area, which is crucial in situations where quick, decisive action is required. The ability to fire multiple rounds in a short timeframe enhances the effectiveness of artillery units by suppressing or neutralizing threats quickly, making high-explosive rounds the preferred choice in many tactical scenarios.

Illumination rounds serve a different purpose, primarily used for providing light in darkness, and do not contribute to the rapid-fire tactics needed for effective combat engagement. Practice rounds are designed for training and practice scenarios, lacking the explosive properties needed for actual combat. Guided rounds, while highly precise, may not be as suitable for rapid fire due to the complexities involved in targeting and guidance systems, which can slow down the rate of fire compared to conventional high-explosive rounds.
