That's what I thought for a long time as well. It doesn't matter whether I play RTW or MTW2, in most cases the unit's experience stays high, but on rare occasions that I have seen in both games the unit loses some experience when being retrained. I don't understand why this happens or what it depends on. Bug? I'd like it to work either way, recruits green or "veteran recruits", but it seems to be a mixture of both. Thus, I'm never sure whether to merge or to retrain.
