I believe this is mostly due to the current state of the community. I remember when I was in the 92nd and we had the NA Company lead by Littlefield, it was always really enjoyable to go to events with them whenever we had the chance.
But at the moment, keeping a regiment active is already not that easy and takes most of your attention as a leader. Having a EU/NA detachment sure sounds like some really good fun, but realistically speaking it's just something hard to maintain.
