Flags Can be stacked. You can put several (the most I have ever done was 4, for 1,000 point, so I don't know if there is a limit on how many flags can be stacked in a single hex). I di several of the maps that come with the game and I noticed that the flags and their values did not 'stick' to the map. Don't know if that was because they didn't stick or someone unstuck them.
In the 'swamp thing' (Basara) map I put doubled flags worth 500 points at the entrance to the maze I so labourously created in the swamp. It looks completely impassable but there is a maze of hidden paths thru the swamp and I was leaving a clue. Not sure if that worked or not. Nobody in their right mind fights a battle in a swamp, which might have been why the Mullahs and Saddam fought there.
