What is a designated defensive marksman?

A Designated Defensive Marksman (DDM) is a specialized security professional responsible for providing precision fire in defensive scenarios. They operate within law enforcement, military, or private security teams to engage threats at medium to long ranges with high accuracy. Unlike standard snipers, DDMs are integrated into a unit and offer rapid, precise engagement to support defensive operations. They typically use designated marksman rifles (DMRs) optimized for quick follow-up shots and adaptability in dynamic environments. Their role bridges the gap between standard infantry and snipers, enhancing a team's defensive capabilities.
