Anybody have any insight in what the right tactics are? How many do you need, in what mix, do fortifications make any difference, any other tips?
Difficult question....
I think it all depends on what you expect to encounter, and what you need to defend.
If you defend against CBs, you can forget about CLABs, their range is just to short to harm ships, these guys are only interesting when attacked by an AA, since the ships will have to come close then, and if your enemy makes it to the shore they will fight along as LDBs. CHABs are terribly expensive, so I think you should only build them in your major cities. Anything under 20 Pop I'd just forget about it. It's less painful to take the damage from the CB than it is to pay for building and maintaining lots of CHABs. And you need lots of them. If your CHABs get silenced, you might as well not have built them. The damage they do to ships is more than a few scratches, but not by much.
So....
* CLABs only in locations where you expect AAs
* CHABs in locations where you expect CBs
* CHABs only in large numbers, and therefore few locations
Weither or not fortifications are worth their cost is another question entirely, and I'm undecided on that one.
