What are the four types of Impact Media used in marine operations?

The four types of impact media used in marine operations are essential for ensuring safety and effectiveness during training and live-fire exercises. Earth's characteristics, such as density and absorptive qualities, make it an effective medium that can effectively dampen and contain projectiles. Water is another crucial impact media due to its ability to absorb energy and prevent ricochet while providing a natural barrier. Steel is employed because of its durability and capability to withstand significant physical impacts, often used in structures that require a robust containment system. Lastly, concrete provides a strong and stable surface that can absorb energy, prevent penetration, and effectively contain projectiles.

This combination of materials serves to minimize the risk associated with ballistic impacts and prevent unintended consequences, making them the preferred choices in marine environments. Other options listed do not encompass the same level of effectiveness for impact media in the context of marine operations, as they either lack the necessary density or are not typically used in such training scenarios.
