I cannot find is this problem are known or not.
Russian version ARMA II Patch 1.02 (Updated to build 58134).
- The defence object can not be build for Russian side in warfire based missions (Warfire, Bear rising). If you chose the Russian side in warfire and begin the game, you can't build defence objects such as walls, MG, etc. The defence object does not appear in the game after menu clicking. It looks as though the menu items are ignored by game. For other sides building of the defence structers is available. AI can build defence structers.
