Through practice. One of basic traits of peer long range combat appears that it's indecisive, and decisive action role increasingly gets transferred to those who can.
Threat posed by current AAMs is such that only very unpeer engagements with long range engagements are decisive.
Otherwise, sides exchange blows, maybe lose a few aircraft if they overestimate themselves, and that's it.
I wouldn't say peer long range combat is indecisive.
We have yet to see what a true peer large scale air war looks like where both sides have the will and the fleet size to suffer casualties in pursuit of strategic objectives.
Arguably the greatest evidence of what a modern peer air war would look like is the PAF-IAF clash earlier this year, and despite the engagement only lasting for less than a night, it was fairly tactically decisive. The only reason it wasn't operationally or strategically decisive is because neither side had the fleet size and the will/rationale to continue putting their aircraft in harm's way of the other side's aircraft, arguably because the initial round of losses was too devastating.
But for a true high intensity conflict where each side wants to gain air superiority and have the resolve and fleet size to push into theater, I expect true large scale peer air war will be devastating and decisive, and it will be determined by the ability to generate high quality sorties capable of out BVR-ing the other side (as the most desirable set of traits inclusive of weapons, sensors, networking, stealth, sufficient kinematics to leverage BVR) en masse, which will prove the highest yield force.
All of which is to say, Heliox is right to say that the these sort of WVR peacetime intercepts and tactical cat and mouse games are not that useful in factoring in the most important ways in which a true large scale peer air war would look... however Siege is also correct in that for the purposes of trying to "dunk" on one side or another, that "WVR/dogfight/cat-mouse game" outcomes is instructive to the common denominator and your pedestrian drive-by person who knows nothing about the PLA.
My question is more why those people's "copes" had to be "dunked" on to begin with.
We all know that, and PLAAF wouldn’t have centered the doctrine around PL-15/16/17 if it didn’t value it.
I just find it extra funny since a lot of the YouTube pilots love bragging how they’ll be able to shoot down J-36 in dogfight and/or Chinese pilots are no good because they fly conservatively in airshows.
I agree with that, but I also feel like even bringing up the matter of said "cope" to "dunk" on them is detrimental to these flagship threads.
I've written many times about why posting those youtube videos and articles or NAFO equivalents is a waste of time for us, because it just ends up mocking their cope and saying why they are stupid for having poor opinions.
Do we really need to reference them when talking about this news, when we all know that PLA pilots have quite good flight hours and are perfectly competent at BFM? IMO actively using effort to avoid/ignore their opinions is more beneficial to us.
