Why the lack of a dedicated AT copter in most northern european armies?

The northern European countries outside of Russia (Denmark, Estonia, Finland, Iceland, Latvia, Norway, Sweden) seem to largely have no dedicated helicopter for anti tank warfare. Mostly the countries rely on some mix of light and medium helicopters if they want to use helicopters for taking on the big iron. The military doctrines in these regions really seem to favor the old one man (sacrificed) for one tank strategy.

Why the lack of a dedicated anti-armor helicopter to do the job?
