It didn't occur to you that with such hard rusks, you have to break them into small pieces and use your molars? These armored crackers are used to fill the stomach. They are not slices of bread. You put such a piece in your mouth and give it a while, and in a while the saliva will soften it enough to chew, and then a piece of pate or mince with a spoon or even a knife. These plastic cutlery are exceptional crap. Any self-respecting soldier does not use them. He has his own accessories made of decent material. As for the chemical heater, you did not read the instructions. After pouring water, it should be folded, not rolled.
