The Joint Service Adventurous Training Wing (Cyprus) have just published their programme for 2018/19 which can be downloaded at the link below. They provide the full range of BSAC courses from Ocean to Advanced Diver, instructor training and a number of skill development courses. This includes training to use Trimix on the Sports Mixed Gas course.
All JSATW(C) courses are available to members of all three services and can be bid for by personnel located both in Cyprus and other locations, including the UK and Germany.
Courses need to be booked through the Adventurous Training Group (Army), aka ATG(A) site on the intranet. This can be accessed from the internet but you will need a valid Defence Gateway username & password.
