Absolutely correct. http://www.globalsecurity.org/military/library/policy/army/fm/4-30-13/apph.htm
There are quite a few types of explosives listed as 1.1D
Without a UNO number not much can be gleaned from the pics.
It is revealing that ABC says 1.1D means it's HMX, when it could ALSO be any of a dozen or more other common explosives including black powder and gunpowder.
Did ABC really say that? Incredible!
The ignorance of journalists always amaze me.
