In the HFRG Weapon Retention Systems, how many types of defenses are mentioned?

The correct answer identifies the structure of weapon retention systems that are taught in HFRG training. There are specific scenarios for when a weapon is holstered versus when it is drawn, which are essential for effective retention tactics. The classification into one holstered defense reflects the importance of securing a weapon that is not actively being engaged in a situation. Additionally, the mention of two drawn weapon defenses highlights the necessity for practitioners to have a comprehensive approach to retaining a weapon when it is already in use or drawn, which is often time-sensitive and critical. This blend of holstered and drawn defenses underscores the varied contexts in which weapon retention must be addressed and provides a foundational framework for practitioners to develop their defensive tactics effectively.
