The troop barracks is a case of someone doing a new building design, pressume its an icon & could be done the same as vehicles but dont know could be in the code I suppose. If some one fancied replacing (adding?) some might be nice. For instance with multi hex buildings there are a few that run \ but none that run /. Also & may be how they work several the place hex is outside the building outline meaning you cant run a road by it. But I am being picky now.
On tents pretty pointless the above is cosmetic tents are purely cosmetic as no defence modifier & scale of the game would probably not effect movement either. Use dirt say tan colour & label it tents.
