CASEVAC
Casualty Evacuation
CASEVAC is distinguished from MEDEVAC by its improvised, immediate nature. Where MEDEVAC is a regulated, dedicated medical evacuation using specifically outfitted aircraft with medical personnel, CASEVAC uses whatever platform is available — a combat vehicle, a civilian truck, a non-medical helicopter — when no MEDEVAC asset is accessible in time.
CASEVAC vs. MEDEVAC
| Factor | CASEVAC | MEDEVAC |
|---|---|---|
| Platform | Any available asset | Dedicated medical aircraft (marked with Red Cross) |
| Medical personnel on board | Not required | Required (flight medic minimum) |
| Planning | Ad hoc, immediate | Deliberate, 9-line request process |
| Protection | Combat aircraft protection rules apply | Protected status under Geneva Convention |
| Speed | Immediate | Governed by mission request cycle |
| Use case | When no MEDEVAC available or time-critical | Standard medical evacuation |
TCCC and the Casualty Collection Point (CCP)
Tactical Combat Casualty Care (TCCC) divides care into three phases:
- Care Under Fire — return fire, apply tourniquet (upper extremity hemorrhage), move casualty to cover. No other treatment unless negligible risk to rescuer.
- Tactical Field Care — out of direct fire, <30 min stabilization. MARCH: Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia/Head injury.
- Tactical Evacuation Care — en route to Role 1/2. Continue MARCH, IV/IO access, reassess.
The CCP is a pre-designated or hasty-selected location where casualties are consolidated before evacuation. It should be:
- Covered and concealed from direct observation
- Accessible to ground or air evacuation assets
- Located outside the minimum safe distance of ongoing fires
Casualty Triage Categories (NATO)
| Color | Category | Description |
|---|---|---|
| T1 — Red | Immediate | Life-threatening, survivable with immediate intervention |
| T2 — Yellow | Delayed | Serious, stable enough to wait for treatment |
| T3 — Green | Minimal | Walking wounded, self-care or buddy-care |
| T4 — Black | Expectant | Unsurvivable or would require resources that endanger others; palliative care only |
9-Line MEDEVAC Request
Even in a CASEVAC scenario, the 9-line format remains the standard for communicating casualty requirements:
Line 1: Location of pickup site (grid)
Line 2: Frequency and callsign at pickup site
Line 3: Number of patients by precedence (U/P/R/C/E)
Line 4: Special equipment required
Line 5: Number of patients by type (litter/ambulatory)
Line 6: Security at pickup site (N/P/E/X)
Line 7: Method of marking (smoke/panel/strobe/none)
Line 8: Patient nationality and status (military/civilian/POW)
Line 9: NBC contamination (N/B/C)
Precedences:
- Urgent (U) — evacuation within 1 hour or patient will die
- Urgent Surgical (US) — requires surgery within 2 hours
- Priority (P) — evacuation within 4 hours
- Routine (R) — evacuation within 24 hours
- Convenience (C) — no time constraint
CASEVAC Planning in the OPORD
CASEVAC is addressed in OPORD Annex F (Sustainment) and Annex H (Signal) (for MEDEVAC frequencies). Commanders designate:
- Primary / Alternate CCP locations with grid references
- MEDEVAC request frequency and callsign
- PACE plan for evacuation: Dedicated MEDEVAC → CASEVAC vehicle → ground convoy → local national support
- Role 1 / Role 2 locations and route from CCP to MTF
