Start with taconite, smelt, deslag with lime, blow oxygen through the melt, pour ingot, pound ingot into forms, use forms to make tools, use tools to build said tank. or not

Rocks are great building materials. My grandfather was a stonemason, and although most of his work involved cut stone, mostly limestone, he said one of his greatest pleasures was to build a wall or road by fitting randomly shaped rocks together like the pieces of a puzzle. Cheaper and less energy intensive than bricks, too.-Jitney

Hard to match the durability of granite. In rural Connecticut you often see rows of granite fence posts off in the woods somewhere with no buildings around. Once there was a house or farm there with a fence around it. The fence, the farm are long gone and just the granite posts left.

Didn't Einstein say that World War IV would be fought with them?
