>>1977214Depends. US Army MREs are light and have everything you need to start eating, but the menu can be tasty, can be disgusting.
Other countries have better MREs, like the Spanish Army, pretty good items and meals, but are more heavy and annoying to pack.
You could make your own MRE buying all the stuff from a supermarket and it would be cheaper.
