Canned, self-heating rations known as Stormtrooper rations were given to Imperial stormtroopers while they served the Empire. These rations incorporated a heating element and could be stored for approximately two decades (years).
While the flavor of the grayish, viscous food was extremely unappetizing, it did fulfill the dietary needs of a standard stormtrooper. Every container of stormtrooper rations had the official Imperial seal, guaranteeing the food's safety and nutritional value. These rations were usually carried on a stormtrooper armor's belt.
