I couldn't find any forum posts for this, and I didn't even bother with the reddit page.

Since we now have weapons and missiles, I would see it only fit that there is some sort of counter measure, like chaff and flares.
I know that most of the missiles are easy to dodge, especially if you know the correct methods to do so, but I think that it would make for an entertaining dog fight if both sides had chaff and flares.

On top of this, I think it would be great if there was some sort of ammo in SP. I know that the weapons update is relatively new, but to have some sort of ammo for guns would get rid of the gun spamming and make the users have to manage their bullet usage. It could also be applicable to the chaff and flare systems (if added) so the user would have to manage the chaff and flares so that he/she didn't run out when engaged by a plane.
