Whats in a bunker?

Added some in a couple of OOBs, more to reflect actual usage than usefulness. Some countries tend to dig in their old tanks a lot to create defensive lines, but I agree with Marcello that they tend to suck a lot in modern warfare.
Think about Switzerland, Austria, Sweden, these countries still use a lot of heavy fortifications like, as I said, stripped-down tank guns placed in concrete or stone structures with large storage and living quarters.
