"The A10 has been fitted with targeting pods for years IRL. Considering the game takes place in the 2030's, it is perfectly plausible to expect targeting pods on all the attack aircraft in game."
No, if there is no TGP visible on the model, why have the aicraft behave as if it had one ?
It's the same as saying "The A-10 IRL can be fitted with 15 mk82, but the Arma 3 model only shows 4, but I want the game to behave as if I had 15 MK82 since that's possible IRL".
If the vehicle in game is not fitted for it, don't make it behave as if it was. Period.
You can probably have a feature like that with an addon. Don't make it for the vanilla game.
