Pishta, in late '66 we were issued C-rats dated 1951 for a while. Tasted fine. Well, except for the ham and mother....... O00ps, family friendly site...... Meant to say ham and lima beans. Can't remember
anyone who liked them. I don't eat pork anyway (its a religious thing), so went hungry when I drew them. I was fairly good at trading and bartering stuff, but you couldn't give ham and lima beans away. They were awful. Beans and franks were my favourite C-rats. And the canned peaches you mentioned. Mothers cookies were pretty good, too.
One of our sons was serving in the Corps when Desert Shield/Desert Storm went down and I went back in as a middle aged reservist on active duty as well (SeaBees that time 'round). Jon was home on leave a couple of weeks before I reported and brought some MREs home in his sea bag so I could see what they were like. I must say they were a lot different than canned C-rats. And I liked C-rats better. Reckon its all what you're used to.
Semper Fi,
Harry
