Never understood why we don't have an Army version of the Davis Monathan AFB Boneyard. If the price of steel, or a national emergency pops up, we'd be glad to have it. Bottom of the ocean? Pfffttt....just as dumb as gun buybacks and destroying guns instead of giving them to the poor for self defense.
I mean Russia still has over 10,000 T34/85s T55s, T64bs etc. sitting in warehouses and boneyards "just in case". A Russian once told me when I asked about all the rusting hulks, and he said, "we throw nothing away. We either sell it, rebuild it, or reuse it. After WWII there was a severe shortage of steel. We will never be in that position again".
I assume it’s still true, but I remember reading years ago that in major conflicts, the country with the most tanks has always won. Not the country with the most advanced tanks. I realize that is very simplistic and isn’t a “guide” to win wars by...but worth a mention given this post.
