If I were to guess, probably all of the months (four to twelve) in units that are in the Arctic, and (very close to) zero months in other units. I also don't know how well military experience from other Danish regions translates to the Arctic. Probably quite well, I'd imagine.
Americans were very efficiently suppressing such ideas. They were never interested in Europe having effective army. They only wanted to sell equipment and partially support their bases with European money. When the school bully is your "friend" you don't exactly have the freedom to do what's best for you.
