The FSR seems to me to be an American version of the 24 hour ration pack issued by the UK and other NATO armies. Each individual FSR pack is intended to sustain a soldier for 24 hours. The items contained with in are optimized for eating on the move, such as while travelling in a HMMWV or an IFV. The content can be heated but appear to be optimized for consumption cold and even appear to be designed to minimize the need for a spoon. There are more individual items in the FSR than in a single MRE but the calorie count of an entire FSR is a little less than three MRE's. The volume of an FSR is 50% of three MRE's. So the trade off appears to be some calories for half the volume and some weight. It would appear that the FSR is not going to entirely replace the MRE, at least any time soon. From my reading, the FSR as conceptualized was intended for sustainment during the first 72 hours of conflict. I gather to minimize the logistical burden of a rapidly deploying unit as well as taking some of the weight off of a soldiers back. The US Military has tried to standardize on a single field ration before and in the 80's thought they had gotten it right with the MRE. it would seem that once again operational experience has taught them otherwise.
