MREs (short for “meals ready to eat”) are the brainchild of the US Military. These convenient, ultra-durable, and super compact meals were developed by the military to replace the heavy, bulky rations that preceded them. Earlier military meals required much more time and resources to prepare and because of their weight and bulk they also required more effort to move. Early rations also left behind a good deal of waste – a clue to the location and movement and number of troops. https://survivalwarehouse.co/pages/mre-meals-ready-to-eat
