CASEVAC in Afghanistan: MERT, Chinooks & the British Medical Chain on Operation HERRICK

Medical personnel working at the British field hospital at Camp Bastion in Afghanistan

The speed of British battlefield medical care in Afghanistan depended on a chain: treatment at the point of wounding, extraction from the contact, helicopter evacuation and surgery at the field hospital.

The Medical Emergency Response Team, usually associated with Chinook helicopters, became one of the best-known parts of that system.

Point of wounding

Immediate care began with the casualty's comrades and trained medics. Control of catastrophic bleeding, airway management and rapid reporting were critical before an aircraft ever launched.

The nine-liner and landing site

Units passed casualty details and landing-site information through the radio chain. The extraction point had to be secured and marked while the tactical situation was still developing.

MERT

The MERT placed advanced medical capability aboard a helicopter so resuscitation could begin during flight. Team composition varied by mission and period, but could include emergency medicine and anaesthetic specialists alongside medics.

Chinook

The Chinook combined speed, lift and space for medical staff and equipment. It could also require escort or careful routing in high-threat areas.

Camp Bastion hospital

Role 3 medical facilities at Camp Bastion provided surgery, imaging, intensive care and trauma teams. From there, seriously wounded British personnel could be evacuated onward through the strategic medical system.

Why survival improved

Survival reflected more than one helicopter team. Better body armour, tourniquets, pre-hospital care, rapid evacuation, blood products, surgery and rehabilitation all formed part of the chain.

The limits

Not every casualty could be saved. Terrain, weather, enemy fire and injury severity imposed hard limits. Celebrating medical capability should not erase the deaths or the long-term consequences of catastrophic injury.
