Shelf-stable rations

The US Army has developed shelf-stable pocket sandwiches as combat feeding rations for its troops on-the-go. The sandwiches are engineered to prevent microbial growth through the use of specialized water treatment, acidic content, special multi-layer foil packaging, and oxygen-absorbing packets.
