I thought the maximum entrenchment level for any stack was 7; so, I was surprised to see the tooltip below indicate a maximum entrenchment level of 3 for the selected stack. I have two questions:
1. What determines the maximum entrenchment level for a stack?
2. Why can I bombard passing ships with this stack when my entrenchment level has not reached 5, which, I thought, was a pre-requisite to attack passing ships with artillery?[ATTACH]25854[/ATTACH]
