I've no idea about berets and badges but I know there were two different type of SF "medic".
The first was the badged UKSF operators who have trained as patrol medics , they did a course which included advanced resuscitation, tropical medicine, basic primary healthcare, advanced trauma management and pharmacology. They also did an attachment usually at local hospital where they spent time in the Accident and Emergency unit /Resusitation room and Trauma/Emergency Operating Rooms. A few passed through (and one passed out !) of Edinburgh Royal Infirmary in the 1980's when I worked there.
The second are Combat Medical Technicians (RAMC) part of the UKSF Medical Support Unit. They had to do a two week 'selection' course , "Black Serpent" , the entry requirement was having Combat Medical Technician class 1 training.
Perhaps they have updated/changed the training or created a "new" unit recently ?
