Since when is "jungle expert" an authorized tab?

I'm a senior instructor at JOTC. The current POI is not graded on a pass/fail basis. We provide one week (6 days) of Jungle skills which include: Jungle medical, patrolling techniques, waterborne operations, ground sign awareness, and rope assisted mobility. We provide the training to the units going through (BN level, with a one week offset between individual rifle companies). The 70% pass rate refers to the amount of injuries sustained. The terrain is very rugged and is something Soldiers are not used to operating in. While Hawaii doesn't represent the heat, flora and fauna as some jungles across the Pacific can provide, it does have a realistic view on the hazards associated with operating in a jungle environment. The training is less like a school and more like a training rotation.

Our cadre have been to many foreign jungle schools across the globe including Malaysia, Australia, Brunei, Thailand, and the Philippines and are continuously going to more.

As far as the Tab goes, it is division authorized much like the "Commando tab" of 10th mountain or the "Arctic Tab" im Alaska and only worn in 25th ID. If any questions about the training feel free to contact me to avoid speculation.

I think it's authorized as local wear while assigned to the 25ID.

Found this on Wiki. The "JUNGLE EXPERT" tab was often worn by graduates of the Jungle Operations Training Center until the school became inactive in 1999. The tab may have been official until 1982. The tab was never recognized army wide, but enjoyed a quasi-official status much like that of the Cavalry Stetson. That is, the tab was often authorized to be worn by graduates of the school by local commanders and by members of the United States Army South specifically.
