I've compiled svn4715, that contains the "capture military building" feature. Congrats for that add because the game get more dynamic and exciting with the battles and territory changes that occur!
But, I have two little complaints:
1) it is no possible to destroy a captured building. Is this on purpose, to prevent "scorched earth" tactics ? If yes, still it would be nice that after a while, it becomes possible to destroy a building. Or to restrict building destruction to the cases when the building is accessible from the HQ or a warehouse by a path ? Which leads me to the next complaint...
2) When capturing an enemy building, it often happens that the enemy territory remains so "influent" that it is impossible to link a road to the flag of the captured building.
These two problems combined make it hard to recover soldiers from captured building.
