Cute.
However, real AP rounds were dyed for precisely this purpose -- ID'ing which gun was hitting where.
The realism argument breaks down, though. IRL, 88mm guns were often guided by radar and gunners had calculation devices on hand for their TEAM manning the gun. IRL, ALL 5" guns were manned, and ALL gunners had training in targeting. In real life, it was VERY VERY dangerous to overfly a hostile carrier group. Here, it can be done almost routinely. Also, in AH (a game for FUN) CAP is nonexistant because (as IRL) it is a boring job most of the time.
Here some guns are automated, and there is no way to learn how to hit targets that are not 2k range travelling tangentially at 3k alt. Most importantly, there is no way to get feedback about your gunning because your misses are invisible-- whcih was definitely not the case IRL. So, you cant till if the puffs are yours, and you cant see your misses -- how are you supposed to get better? There no other task in AH that has to deal with this handicap.
While I understand that non-furball topics draw sarcasm from some BK's, I'd think you folks might be a little more sympathetic. After all, inability to defend carriers from "lone dive bombing fun nazi buffs" and the like generally kill a furball more permanently than any other event in AH. If you go ballistic over a FH killer, why are you dissing the only base weapon that can reliably stop him from an FH kill that takes hours to repair (ie CV death)?
