In game such barb wire effects are turned off for vehicles including planes, so planes would be unaffected.
Funny thing is WWI tanks had a real pain with barbed wire getting caught on their tracks.
So why would people be concerned with barbed wire on an airfield?
So yes, if I somehow manage to penetrate the enemy's lines with a truck and deploy barb-wire, that's not me being a smacktard, it's the enemy being incredibly incompetent.
Not really, you would still be a smacktard.. as there are no "lines", just random units running around, getting to an enemy main is quite easy in a fast vehicle like a truck. :rolleyes:
