125 calories a day is 1/10th the minimum recommendation for someone on a diet. It would appear to be too little for subsistence. As for military rations, they are very calorie heavy and designed for long term storage if kept in a relatively cool, dry, shaded location. MREs (Meals, Ready to Eat) are typically rated for seven years if stored this way. In the early 1990s I was inspecting one of the MRE production manufacturers in Texas and the facility manager showed me some 1967 Vietnam era C-rations (actually dubbed "Meals, Combat Individual" or MCI, but still called C-rations). He said he had recently opened one and found the food still edible, even though it had been made 25 years prior.
