This map has many logistical issues.
First, if the blues are defending, you can set up neighbours to be one way towards the blue bases, so that they never attack the reds.
Second, neighbours should only be adjacent: red's bridge base should not be attacking the boat, for example.
Third, there are actually very few oprtions for red to attack from. The blue base is almost completely sealed off, and the other two blue flags are impossible to attack without winding through the one gap in the base's fence. There is no point in having a huge defensive barricade in front if the bots will never attack from that angle. Boats also cannot land anywhere but at that base.
Fourth, there there too many planes/turrets; on 50 bots, 18 of red's 25 men are in bombers. 2 bombers and 2 flak is plenty.

I really like the design of the millitary base though, it's so cozy. If you can straighten out the logistical problems, this can actually be a pretty fun defence map.

More screenshots please?
