I suspect that many nerds already know this, but here’s a data point from the document about which I blogged yesterday:

The Soviets have a wide variety of tactical nuclear weapons. The number of nuclear capable and potentially nuclear-capable artillery cannons has increased by well over a factor of ten in the last decade.

Hans Kristensen and Matt Korda place the number of Soviet TNWs at “13,000–22,000 in the late-1980s.”
