Casualty Clearing Station

In the British Army and other Commonwealth militaries, a Casualty Clearing Station (CCS) is a military medical facility behind the front lines that is used to treat wounded soldiers.

A CCS would usually be located just beyond the range of enemy artillery and often near transportation facilities (e.g., a railway).

The CCS receives battlefield casualties from regimental aid posts located in the combat zone.

On 1 March 1970, the Royal Army Medical Corps went through an internal reorganisation which saw the old medical designations replaced by modern terms.

The field ambulances meanwhile, as the name would suggest, were mobile units equipped with Land Rover Ambulances which would support units on the battlefield.
