A barracks add +2 to the owners Combat score and 2 Trade. A scout allows you to effectively block or steal the benefits of an opponent's buildings by standing on them.
When I have a scout on an opponent's barracks what happens with the Combat score bonus?
- Do I steal it? (His score:0 Mine:+2)
- He just loses it? (His score:0 Mine:0)
- Or nothing, I just get the trade? (His score:+2 Mine:0)
