This simulation trains corpsmen to execute Tactical Combat Casualty Care (TCCC) in the confined, high-risk environment of a helicopter assault ship—where space is limited, lighting is variable, and help is often minutes away.

The learner begins with a simulated call for help from a passageway below deck. Responding alone, the corpsman must locate and begin treating a simulated casualty with injuries ranging from hemorrhage to airway compromise. The scenario places learners in a realistic, time-sensitive environment where rapid action must be balanced with situational awareness and self-protection.

Treatment decisions are performed within the learner’s scope of practice, mirroring real-world expectations of Independent Duty Corpsmen (IDCs) and junior medics during the initial phases of shipboard emergencies. It reinforces prioritization: hemorrhage control, airway support, and hypothermia prevention—TCCC pillars that hold even in maritime environments.

When the higher-level provider arrives, the corpsman delivers a verbal MIST report—Mechanism, Injuries, Signs, and Treatment—communicating critical information for care handoff. This exchange marks a transition in responsibility and tests both the medic’s clinical recall and their ability to speak clearly under stress.

Shipboard scenarios like this one help simulation trainers develop competencies often missed in land-based trauma drills. Learners must contend with structural barriers, radio comms issues, and the cognitive load of operating without immediate backup.

For trainers, this simulation enables focused evaluation of care under isolation, maritime TCCC readiness, and handoff accuracy. It’s a compact but high-yield scenario that challenges not just clinical decision-making but role clarity and composure—essentials for casualty survival at sea.
