Yeah, the american MREs I’ve had before came with a big plastic baggie with some chemical stuff in.
Pour in water, boom instant heat enough to cook some rats. It gets damn hot, I nearly burnt myself.
The english ration packs I’ve had were pretty nice, but at the time we still had to cook them in a mess tin with a fire, although I’m sure active forces have gotten some kind of heatpack now. Nothing quite like entering a battlezone-- only to have a relatively nice meal finished up with treacle pudding.
Still, gotta remember though MREs can be eaten cold and they’ll still provide enough nutrition.
Maybe have an option to use water on MREs to make them cooked, Hot and more enjoyable?
And remember folks just because the food isn’t to your taste, it’s to ensure a soldier in an active environment gets enough calories and doesn’t end up starving halfway through a firefight. Imagine, you’ve been trekking for hours through some inhospitable PiTA desert, up to your asscrack in sand, your convoy just hit an IED and the natives have been taking potshots at you all day-- I’m pretty sure even the most terrible ration would taste like Ambrosia. Besides, most of them come with Tabasco sauce to drown out the flavour.
…Oh, and by the way, ignore all that. Cold or Hot, that treacle pudding is fucking horrendous.
