Combat Medical Technician?

I got given the chance to do CMT after my barb test, because it is a advanced job and if you wanna do it your head needs to be screwed on at all times with any job in the army its the same. you don't need any qualifications to do the job but your tested with the aptitude tests during the recruitment process, yes they will carry weapons with them because whats the point in running towards injured soldiers on the frontline without a weapon? have a look at the link below. and by the way a few people are saying there is no such thing, yes there is I have the job available for me to do, it is the British Army not the American Army
