When the US went to war, Mars got an exclusive contract with the US military to provide M&Ms for C-Rations. M&M candies, named for the first initials of each partners’ last name, went on sale late in 1941. By making a deal with Bruce Murrie of the Hershey Corporation, Mars had access to rationed chocolate. M&Ms – the chocolate candy surrounded by a hard candy shell – were patented by Forrest Mars on March 1, 1941. In civilian life, we know these as M&Ms, instant coffee, and Spam. Within these rations, soldiers found candy, freeze dried coffee, and canned meat.

They provided between 3,000 and 3,600 calories per day. K-Rations and C-Rations were both issued to troops in combat. This system was designed to “maintain the health and effectiveness” of the troops.

The US military had a system of rations for feeding troops in the field. It includes a packet of Nescafe instant coffee, energy biscuits (they look like crackers), gum, a tin of chopped ham and eggs, the key to open the can, and cigarettes.
