A long time ago, when I was in the old Army, we had to eat some canned crap that was issued in a little brown box. This crap was called "C-Rations." I was a skinny kid it those days.
Now they give you some stuff called "MREs" Meals Ready to Eat. It's still crap, but it's all in a different kind of package.
I've read some books about the Civil war, WWI, WWII etc. They all had crappy food for field rations. Why does the Army do that? After over 200 years of tradition unchanged by progress and they still give us crap when we go out in the field.
Oh well, nobody listens to a soldier at my level. Generals pick the crap we get, then the company they gave the bid to gives them a job when they retire. We get so much crap for equipment and software now. Last year when we were doing our 2 weeks of Army training, I had some high ranking computer nerd type officer start to tell me about some new software the Army was working on. He was telling me how it would be able to do the work we do and make things so much better.
I listened as polite as I could, then told him: "Sir, I don't care what kind of computer stuff they come up with, they'll still need people like us to go out into the field and do the job....Sir!"
The Sergeant Major was standing next to the nerd officer...the Sergeant Major wanted to "talk to me" later. He told me that I might have offended the nerd officer when I said they'd still need people like me to go out and get the job done. I looked at the Sergeant Major and said: "Sorry, but it's the truth."
The Army can give you hard tack & beef jerky with pork fat, they can give you C-Rations, they can give you MREs. But, what they'll never be able to replace is the Soldier who has to go out on foot and get the job done. Whatever the job is.
