Sometimes you will be selected to attend the combat diver preliminary course (prelim) through your own request...sometimes, as in my case, you will be told you are taking the prelim. It is scary as hell to be told...but an honor none the less. Whether you are selected from a pile of requests or just told to do it, you must show that you have some level of capabiity and determination to warrant putting your name up the chain of command. DO NOT TRAIN FOR THE PRELIM!! The dive team does not want a soldier who needs to train for an operation...because sometimes they come out of no where. You cannot train for an operation that surprises you. These were the words spoken to me when I asked what training I should do. If you want an upper edge for the prelim, take a civie dive course and get familiar with the underworld.
The prelim is two weeks long and it is alot of pain...mental, physical and sometimes emotional. Your strength, stamina, endurance, memory, inteligence, fear of drowning and will power will all be tested. On the prelim you will be in pain and you will be hurt, it is up to you only whether or not you can overcome both. No matter if you pass or fail the prelim...you will know what you are made of by the end. You need to know diving, diving physiology and gas laws, explosives calculations and the physics of their reactions underwater, and don't forget the use of the many pieces of equipment at our disposal.
If you have asthma...don't show up, not a fan of pain...don't bother, a heart murmer...don't show up, closterphobia...try again, a fear of the dark or being alone...don't show up, don't work well with small teams of highly motivated self supervising technicians...guess what? If you are not a good swimmer...NO ONE CARES!! One candidate on my prelim almost drowned during his swim test...he became one of the best combat divers I've ever seen. Neoprene helps you float so just pass the swim test. A 70% drop out/failure rate on the prelims is not beyond the norm. The prelim is a pass/fail go/no go situation...but there have been exceptions in extreme cases. On my prelim only myself and one other passed, but four of us were sent and all of us passed the course. The course is now 10 weeks long and although there are slower times on the course than the prelim, it is still about as fun as surfing a rockslide. The course is run in both Gagetown, NB and Halifax, NS.
If a reservist is a combat diver, then he was once in the reg force. If he was never in the reg force, then he is most likely only a ships team diver. If niether is the case and he IS a combat diver, then he was once a ships team diver and he trained with the combat divers long enough to get a bypass...there is no other solution. A combat diver in Canada will always be a qualified combat engineer...no exceptions. Any more questions...you know where to find me...cheers.
