I completed the door supervisor upskilling course in May 2013 with british military security . I found the training staff helpfull and prepared to answer any queries I had and the course on the whole was well run however there were aspects that I feel could have been better and more thorough, especially the basic first aid segment which was barely touch on . I'm sure that these issues have improved since then and to be fair to BMS it was the first time they had run the DS upskilling course.
