- Some people turtle, some don't. It's a matter of how you want to play in your sandbox. If you wait out a siege the invaders leave after either one season or one year (seemingly random selection of one of the two).
- Once dorfs enter combat they're out of control. The only way to somewhat control them is to station them at a location out of sight from the enemy and then either order them to attack or lower the drawbridge. Note that changing stations is not recommended, as dorfs tend to shed their armor in favor of new shinier pieces coming off the production line when changing station, as well as sneak off to stock up on booze, food, armor pieces, or sleep.
- You can improve your fighting odds by using drawbridges to cut off some of the invasion force, letting your dorfs hack up a few enemies at a time. It doesn't matter how good a dorf is, as eventually it will be overcome by fatigue and get killed by an invader who removes the helmet of the unconscious dorf and cuts the throat. Thus, they need time to catch their breath in between the waves.
-Marksdorfs need to be kept locked up so they're blocked from charging when out of bolts. Note that the morons suddenly get genius level pathing intelligence when it comes to charging, you your containment has to be good. They'll easily scale walls and fortifications, for instance, so you need a roof.
