While the Racion de Combate have been pretty constant over decades, with only minor changes done to it, still the Ministry of Defence has been working in conjunction with companies like JOMIPSA to produce something better, although, reluctant to change...
But until now, all of them used heating systems based in solid fuel, examine stoves. These stoves, because of the fumes they release and the open flame the military deemed them unusable inside vehicles and other confined spaces, so unless the army planned on leaving tank operators, soldiers on transports and many people eating cold meals for the rest of their service

And thus, the Ración de Efectivos en Desplazamiento (RED) was developed, a ration a lightweight and compact ration designed to fit the use case of operational teams where the use of the traditional heating systems is not feasible.
The RED is packed similar to the MRE for ease of transport and keeping it waterproof, this ration provides around 1.300kcal and its self-sufficient, it has a 2 year shelf life and the menus are tailored for cultural and religious preferences (halal and vegetarian) its packed in a polyethylene/polyester bag labeled with the army crest and the Menu sheet, contents, and BBD. Until now only two menus have been developed, more to come and quite possible, more to come and substitute the current Spanish racion de combate...
The menus have been designed keeping in mind the preferences of the FAS (Spanish armed forces) members and the guidelines of the army nutritionists
The menus come with two! (this is an 8h ration...) entrees in sterile plastic containers, similar to the ones in Portuguese rations I think, and designed to be used in combination with FRHs
Menu 1: Valencian paella and Meatballs with tomato sauce and peaches in syrup
Menu 2: Ravioli bolognese and beef stew with pears in syrup
