Last week I was helping a firefighter buddy move and at the end of the move he gave me a box of stuff that he thought I might like. Inside were a bunch of little odds and ends that hes' collected over 20 years in the Army (he was correct about me liking.) I was excited to see a few boxes of trioxane included! I was disappointed though when I opened the triox box. I remember this stuff as being about 2.5-3 inches long and scored so you could break it into three pieces. This was about the size of a silver dollar? I know that the military no longer issues Trioxane but when did the smaller bars happen?
