None, because there is no such course to turn you into a "Specialist".
The International Jungle Warfare Advisors course (Belize) is just that..you are qualified to advise on training, it does not make you an expert/specialist.
You also have to be a minimum of Corporal (Sgt for Brunei) and the course normally only takes in groups of 6-8 so you better have some mates to go with you.
As the course is 6 weeks plus 4 days pre-course acclimitisation, you better have an understanding boss who believes jungle training is going to be useful to your unit.
I have spent a lot of time in the jungle in Brunei both in the military and as a civvy, and each time I was up the Ulu I lost a good stone in weight. It is extremely demanding both physically and mentally.
PrinceAlbert: I'm currently in the process of sorting out joining paperwork, so no I'm not yet even in basic, but I'm just interested in looking down possible career paths.
2/51: Assuming that's a no-no then but if I ever did get the go-ahead, I understand the demands the jungle places on an individual. It's nothing in comparison but I've spent a week hiking (pretty bloody quickly) in the Indonesian rainforest and lost a good 5-6lbs despite the huge servings of rice and 'Piri' fruit we downed.
