"the real success of M&Ms apparently came when it was issued as part of U.S. service personnel rations because its hard outer shell made of sugar prevented it from melting before being eaten. Soldiers came home eating M&Ms, and its particular appropriateness to all climates was encapsulated in the slogan (coined in 1954): “The milk chocolate melts in your mouth—not in your hand.”M&Ms were not the only chocolate issued to soldiers. The Hershey company, at the request of the army, developed a chocolate ration that would sustain a soldier who had nothing else to eat and could be carried in his pocket unmelted. Throughout the war, Hershey turned out a half million bars a day of “Ration D,” a 4-ounce, 600-calorie chocolate bar."
