United States military ration
（重定向自Iron rations）
The United States military ration refers to various preparations and packages of food provided to feed members of the armed forces. U.S. military rations are often made for quick distribution, preparation, and eating in the field and tend to have long storage times in adverse conditions due to being thickly packaged and/or shelf-stable. The current ration is the Meal, Ready-to-Eat (MRE).
