The MRE has led to the creation of several similar field rations.
For servicemembers with strict religious dietary requirements, the military offers the specialized Meal, Religious, Kosher/Halal. These are tailored to provide the same nutritional content, but will not contain offending ingredients.There is also a special meal certified for passover requirements.
The Humanitarian daily ration is a self-contained Halal meal designed to be given to refugees and other displaced people. It is designed to feed a single person for a full day, and the menus were intended to be palatable to many religious and cultural tastes around the globe. It is created and packaged much like MREs.
The Meal, Cold Weather provides a ration similar to the MRE designed for lower temperatures than the MRE can withstand. Clad in white packaging, it offers a freeze-dried entree designed to be eaten with heated water, the same side ingredients as the standard MRE, and additional drink mixes to encourage additional hydration. The MCW replaced the Ration, Cold Weather.
The Meal, Long Range Patrol is essentially the same as the MCW, but with different accessory packs. The MLRP is designed for troops who may receive limited or no resupply, and weight of the ration is critical. The similar First Strike Ration is along the same lines, but requires no preparation and may be eaten on the go.
The Tailored Operational Training Meal provides a lower calorie count for less intensive training environments, such as classroom instruction. The TOTM allows troops to become familiar with the MRE and its contents without providing an excessive amount of calories to troops who will not necessarily burn them.
The Unitized Group Ration is a ration much like the MRE, but expanded to feed large groups.The Food Packet, Survival, General Purpose, Improved is given to pilots and other servicemembers that may require a small, extremely portable food ration for emergency situations. It contains food bars and a drink mix. Similarly, the Food Packet, Survival, Abandon Ship and Food Packet, Survival, Aircraft, Life Raft are fitted into the storage areas on lifeboats.
