I would have to disagree John, we are prob talking about strat bombinh the Ruhr area since in Bremen you can get around from the ocean. If you have an AA unit in Holland and one in Ruhr, 1/6 chance to bounce back in Holland, and another 1/6 at Ruhr. That's 70% of your air units will go thru. If you use the proposed rule, that's 16AA factors in the Ruhr area, 75% of the air units will go thru. So at the first example you had a 30% success rate but you had to spent 10 PPs to accomplish that, at the second example you had a 25% success rate but you didn't spend a single PP. the 5% difference will be negated with the extra fighter you will be able to build with the 10 PPs that you didn't have to spend on AA units. That's some ideas to make the game a little more realistic
