Another thing I'll discuss concerns "B-3" Units..... While I was in service I was fortunate (I guess?) to have seen (or eaten) through a few MCI changes / improvements. I'm not sure they were all "improvements" however because as always, G.I.s bitch at just about everything. One sad loss was the first type of B-3 Unit I was issued during my Army stint.
The original B-3 Unit (as I was issued) was a large can which contained 3 large, thick vanilla cream-filled cookies, 1 thick chocolate (or "chocolate fudge") wafer (labeled & wrapped seperately in white waxed-paper), and 1 of the very small, thin cans of jam.
The B-3 Unit was always packed in that order: cookies / candy / jam, from top to bottom. As the heavier jam can was on the bottom, I suppose the candy wafer acted as a cushion between it and the cookies. Surrounding the 3 cookies (top, bottom, and sides) was a thin piece of white "corrugated" paper to help cushion them from the top & side of the can, plus a small round piece between them and the candy wafer as well. Inside these earlier B-3 Units the jam can was not olive drab (green) in color --- it was a gold color. And I only remember 4 types of jam....Pineapple, Seedless Blackberry, Grape, and Apricot. The candy wafers seemed to be made of that special "heat resistant" high temperature-melt chocolate (sometimes called Tropical Chocolate). They were not very good to eat alone, but were good when cut up or "shaved" in to very small pieces and then put in to your hot coffee or hot chocolate.
The best thing about this ration was the cookies --- they were absolutely heaven! I'm sure you've heard people talk about Pound Cake and Peaches being the "best" units in MCIs.....well, the cookies were right in there too! These original B-3 Units were highly sought after and traded for because of the cookies. Truely tasty, and wonderful with a canteen cup of coffee or hot chocolate!
At some point some chair bound idiot decided to change the B-3 Unit (the bastard!). The unit went from the large sized can down to the normal sized small can. The contents changed to 3 round crackers and 2 small, very thin, round chocolate "disks". Each disk was wrapped in foil and made by Hersheys. Although they were very good (far better than the old style thick wafers), they melted very easy in hot weather (or inside your blouse pocket --- unfortunately

Thanks for listening to the ramblings of an old 11 Bravo "Ground Pounder". It's amazing what one can remember from 25 to 30 years ago --- especially since I can't seem to remember what I had for dinner last week! Taco Bell maybe.......burp!
