This vehicle class will be lightly armored good vs aircraft and infantry and will help mitigate air superiority a bit
For the Americans of Normandy a M3 Halftrack with a M2 Browning quad mount.
For Germans of Normandy you have Either the Ostwind or the Wirbelwind.
For the British of Tunisia you have the MK VI light tank with 4 Besa machine guns.
For the Italians you have the SPA-Viberti AS.42 with a 20mm gun
I have two big issues with your proposal
These SPAA are quite varied in terms of protection. For the Germans and Brits you have SPAAs built on tank hulls with armoured turrets. America’s M16 is a somewhat armoured half track and then Italy is the odd one out with a fairly open and armourless car. If SPAAs were to come to came, I would hope they would be a bit more balanced, for example Normandy could have a M16 versus a Sd.Kfz.251/21.
And this is my main issue with your idea, none of these are going to be used against aircraft 95% of the time. Instead people will spawn these, park them on a path out of spawn and reap the rewards. I mean just consider the damage output these will have on infantry, there is a reason the M16 earned the name Meat Chopper. At the end of the day, I think its a terrible idea to put any SPAAs in the game because the small amount of good they will do against CAS will be outweighed by the impact on ground combat. The only solution to having SPAAs in the game and not having them ruin infantry combat is to add in ones such as the Mobelwagen:
hopefully we will get this if we get large scale maps
100% see the second one happening… me being one of those people 
And I think that’s fine it will promote infantry to actually use anti tank troopers more as most of the vehicles I posted would be easy to kill with them. Heck all of them are open topped vehicles so they are vulnerable to small arms fire and regular grenades…
Also these would be pretty much at the mercy of any tanks they come across.
It’s not fine, the SPAA you suggested all possess a killing power that can’t be countered by infantry, and there’s not enough tanks to stop them.
infantry can counter it thou with AT weapons, the splinter shield would not be able to to stop anythink short of light AT weapons
Imagine a scenario for a minute, this is a scenario which already happens with Panthers.
Normandy, Allies are charging up the beach, Wirbelwind is sitting back on the hill, raining 20mm down range. Only way to kill it in that scenario is via bombs, AT rifles (if they were in the campaign) don’t work at range or quickly enough, and the Bazooka is useless at range.
Imagine a scenario for a minute, the map has that much room that you can flank, or light it up with MGs off a plane cuz its open topped?
Flanking is easily said, not easily done especially when it has proper infantry support. With Enlisted’s current DM it wouldn’t be killable by MGs due to Enlisted not registering open tops
well then that is a game play issue, also all of the armored flak vehicles have god auful depression
There is no gameplay issue, the game is perfectly fine without SPAA
As for depression it varies heavily by the SPAA, some like the Mobelwagen can’t fire below a 15 degree angle whereas the Wirbelwind has quite decent depression
its dull, to me this game is about the same as any other ww2 game, but the only thing that it offers is AI bots, if they were to add large scale maps and add light skin vehicles, halftracks and armored cars it would be a great game
also the game was perfectly fine with out the FG42, the m2 carbine and the the AVS but eyt here we are adding more stuff, so why not add SPAA’s
Because the game already has guns, it doesn’t have SPAAs
Okay, then go play SPAA in another game
well lets add it and make it closer to a real ww2 game
It already is a “real ww2 game”
At this point is fairly clear you just want SPAA to rack up kills in
what a childish response
no i just want ww2 game that has all elements of combat rather then just boots, tanks and planes
