- how about adding a Y slots specially for the AAW gunner and machine gun?
-A : that is a NO NO,athough it is good but will invloves of whole game system
to be altered.
- About the US AA gunners:
-A : well apparently it need adjustments also the Type A gun, details in Page 4

I aren't a pro in these but just hope this would have given a opprotunity for
us to play our game with a wider range of choices,

Adding this gun sure might make lags if many players spray these shell to the sky,
but look at the bright side,

-> it does give another option for Close to mid range AA option
-> give another option for beginner~junior players to have a better (well maybe)
guns that have a higher % to hit planes within in ranges
-> solutions for ships that have small secondary weapon slot to load AA guns
-> Better way out for the beginner FF~CL's, giving them a solution that they can
be 'combat-effective' rather than 'rush and die' 'blocking Capital ships' in GB/GBII

i'm expecting negative comment to this, but please, i'll be glad to see
some comments that state why it is not a good idea to put it in to the game.

Well as we all know, before the KM SS4 comes out with it 'overpowered' flak38 quad,
there only the pompoms is the guns that smaller than 3" with AA ability,
but after the flak38 comes out [but before French comes out too],
than i start to think :
Now we got 2 existing AA/machine guns that is way smaller than a 3",
but meanwhile they sometimes can be seen onboard a ship structure,
why not making all these AA/machine guns that we can see in the game to come to
service?

As i said above and another post in this section did talk about,
like the USN, it isn't hard to find a 4x40mm bofors onboard a ship,
but all we can do is "watch it in the shipyard,look how it firing meaningless Auto AA
to the sky and not hitting a darn plane"

So, then i look up the web and bunch of history books about weapons,
then i got this list of AA's that maybe ideal to add to game,
Which is merged with Mattmaster56 ideas and comments given:

Japan - Suckish AA, good luck to those fellas. | Comments by Mattmaster56

United Kingdom - Plenty of options, they shall do quite well. |by Mattmaster56

1x 20mm Oerlikon lvl 12 Arm Sailor
1x 40mm Bofors lvl 18 Arm Sailor
2x 20mm Oerlikon lvl 18 Arm Sailor

2x 40mm Bofors lvl 26 AA Gunner
8x 2 pdr Pom-Pom lvl 42 AA Gunner <---------- Reduced lvl
4x 40mm Bofors lvl 44 AA Gunner

* Judging by the UK forum it seems the UK will be at a disadvantage
if they class their sailor to AA gunner too soon because it will decrease
their effectiveness with larger caliber guns...oh well.
[My quote: well acutally UK AA gunners if not delay class until lv80 it is almost...]

French MN - Good options,
especially for cruisers since they have a lot of t slots.|by Mattmaster56

*Also there was a land based aa gun called the 25mm Hotchkiss, never used in
the navy but had France not been defeated so quick in the war maybe there would
have been a naval versions as well

Mattmaster56 comment on Guns cal. :
Anything smaller than 20mm is ineffective in my opinion which is why I didn't include
the japanese and french 13mm AA Guns.

What would also be great is if they added a few extra slots that can only hold these
smaller aa guns since quite a few certain ships lack enought slots for effective aa
such as the bismarck. Also none of these should ever have HE added or we're
screwed.
