Tactical divers are tasked with some of the most dangerous missions on the battlefield today. Even these operations, which are considered routine, require equipment of the highest standards to keep operators healthy in harsh environmental conditions.

Combat diving requires specialized equipment and exposure to environmental elements not generally found in other military exercises. As an advanced diving technique, combat diving relies primarily on closed-circuit breathing apparatus, fast/low-profile boats, and fine-tuned teamwork. Operating in hostile environments requires expertise beyond the standard of even the most highly trained elite combat branches.
