Hershey’s designed a customized chocolate bar for the troops during WW2 called “D ration bar”. It was so thick that soldiers had to shave slices off with a knife before chewing on it. By the end of the war, more than 3 billion ration bars had been produced. Also, M&Ms were originally made with Hershey’s chocolate, who had control of the rationed chocolate at the time, and were sold exclusively to the US military. They were designed based on a British made candy which was observed by the Mars Company founders son in the 1930s during the Spanish civil war. Regular chocolate was susceptible to heat and the candy coating helped to allow it to “melt in your mouth, not your hand”.
