I have most definitely fought them, because contrary to your belief they are not exclusive to germany!
And how exactly? I have never complained that my stingers are worthless and I cannot fight back against planes. The skill issue is definitely on your end seeing that you ignore all advice and do not change how you play even though it clearly isn’t working.
Please read:
Good thing they can only fire 4 in relatively quick succession. After that they’ll either have to reload from internal stowage or first get ammo from ammo box and then reload, both of which take a lot of time.
Most IRs are useless at closer ranges as they’re basically dead for a first second after firing and simply don’t have enough pull to hit you.
Ozelot has 0 AT capabilities, M247 has some.
That thing has tracerless HE-VT which are actually as good or even better than Stingers in plenty of cases.
At short range M247 is definitely better to have.
At medium range IRs are better.
At long range both are crap.
Ozelot can’t do anything to any ground vehicle in the game and can only fire at aircraft.
CAS can hurt everything on the ground and can also engage aircraft.
This depends as missiles don’t see buildings and they will gladly hit them if their tracking system says so.
It does matter as they are permanently locked in the same field as ground vehicles, so defending themselves against ground enemies is a factor.
Air is by far the most versatile type of vehicle and AAs are the least versatile which is perfectly shown by SP costs.
It’s better than not being able to fire at em at all bc they’re only visible for a few seconds at a time.
They don’t need to fight ground vehicles, but this also doesn’t excuse vehicles like the Gepard which can engage both ground and air VERY effectively, and still has reduced cost.
Compared to tanks, air is less risk for less reward, until you get to ~8.7-9.7 where it’s higher risk for less reward.
Why would I spend 500sp on a plane with a max potential of 4 kills, and massive risk fighting SPAA, whilst I can spend 100 sp for a Bradley and get 9 kills with basically no risk sitting in one spot whole game?
