Wasn't really sure which board this belonged to but /out/ seemed as good as any. Do any of you use and recommend military rations as good backpacking sustenance? Perhaps not solely but serving as a high calorie base and adding other stuff too? What sort of stuff would serve as a good supplement to them? Those who do have experience, what are the pros cons? I've heard constipation is an issue but that seems easily resolvable if you're prepared for it.

I had a mate in the TA(brit army thing) back at uni and she offloaded loads of her 24 hour ration packs to me at the time. I remember they actually tasted pretty awesome and were really quite substantial (hence why she never finished or even cracked them all open). But I wonder do other countries have better rations? And where is the best place to go about buying these sorts of things?
