I know I have been retired for quite a while, but those look like Mk 1 Mod 0 sausages, NSN OU812 (yes, I was Navy, but lived on an AF Base for two years during my service). One time on the menu they would be Italian, the next time a Brat, then a Knack. I hope they taste better now. No matter what kind they were, I know they were enjoyed by all who attended. Now, the next most important question, what were the sides? I, too thank you and your Comrades in Arms.
