(CLS)
The Army battle doctrine recognizes the battlefield constraint on trained medical personnel available to provide immediate, far-forward care. The Combat Lifesaver was developed to increase this far-forward care to combat soldiers during the Golden Hour.  By doctrine, at least one Combat Lifesaver (CLS) is required for every squad, team or crew. The CLS is a non-medical soldier trained to provide emergency medical care. The training received consists of enhanced first aid procedures and selected medical procedures. This training is the bridge between the first aid (self-aid/buddy aid) training given to all soldiers and the medical training given to the combat medics.
