Yes, there is a lot of improvements to make for the Arsenal.
Some things that I didn't mention (since less important) were :
-Do not auto add attachements to weapons.
-Do not keep showing attachements when there are none (go to a profile, put an attachement on a weapon, load another profile with the same weapon but no attachement... boom! the attachement appears as if a part of the profile...)
-Do no auto add item when clicking the category (ex: auto adding Binoculars simply because I clicked on the category.)

And that's just some of the many things that could be improved.

That's what addons are for. There are already plenty of mods to add said uniforms, and they have absolutly no purpose being in vanilla Arma 3. It's the same with M4, there are dozens of mods for the AR15 family...
Download the addons already.

I confirm that it also does that with other GLs, including the ones from addons.

"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.

If there is no TGP present on the aircraft, why would behave as if it had one ? Why would you be able to lock onto a target if your aircraft is not equipped with systems to do so ?

"apart from freefall and TV guided weapons, most guided weapons are laser guided"
AGM65 mavericks ? heat seeking.
JDAM ? GPS Guided.

So yeah, let's take the most successful CAS aircraft : the A 10. Appart from GBUs, no freaking laser guided weapons, ever.

If you have a JTAC, just communicate with him !
