[Chiroone]

Hershey use to make a candy bar they called "Tropical Chocolate" which was issued from WW II to Vietnam. It would not melt as readily as their regular product. It was often included in survival kits in the past. It was then re-issued in the Gulf Wars; and then surplus bars were packaged as the " Desert Bar", I think it flopped and was not well received by the public. I have not seen it lately and am not sure they still produce it.
