What about building objects?

[KnightFandragon]

There is no base building in this game and as far as I know no way to make a building produce anything except protection from an incoming 150mm Shell ready to reduce your infantry's rumpus into a gooey, bloody mass of mush.

There are Sandbags and Tank Traps and Barbed Wire in the game but only online and given only to certain units. if you want them in the Singleplayer Campaigns then just edit them in the mission or the troops invnetory
