Armour

I wanted to have a general discussion about developments in the world of tanks, APCs and ICVs.

To start us off, I have a question: Most of the worlds tank producers are equiping their sensor suites with thermal imaging equipment but MMW radar can produce a near-photographic image at greater ranges and can see though light foilage etc much easier. Why are tanks not being equiped thusly? This would have significant implications for nations like Russia which are famously behind the “West” as far as TI tech is concerned. Why, damn it, why?
