Many players have suggested the features to lay minefields.
This is the true use of mines, not magic candles stuck at rally points
Such functionality would be possible and very appropriate in the BigAction gamemode.
Now I have found a suitable way to add such feature.
As a defensive force in Volokolamsk, the Soviet Red Army can now construct a special ammunition box that will 7 pickable mines. You can arrange them one by one.
This ammo box can only be constructed once within 5 minutes.
This special ammo box building is unlocked by the AA gun technology. You can only use Engineer squads to do this defense work.
To avoid performance issues, mines do not persist permanently, they automatically deactivate after 20 minutes
Note that enemies may also pick up mines that you have not placed. Please make sure the surroundings are safe when laying out minefields.
Thanks to the developers for providing us with a size enough map with their awesome game engine to add many WW2 stuff.
