Recent combats:
IIRC the US shot down a couple of Iraqi aircraft during enforcement of the no fly zones before the eventual invasion which ousted Hussein.
Tactics:
It’s been a bunch of years since I’ve done this, but the big picture AFAIK is unchanged.
That article was written by somebody who does not know what he’s talking about. He’s not wrong exactly, but it’s apparent he’s just regurgitating factoids out of a cookbook without ever having turned on a stove himself. The cookbook he’s working from is bog standard stuff from my era, the late 1980s.
Air to air missile (AAM) warfare is conceptually similar to sword fighting without shields. You and the other guy have similar, but not identical offensive tools. And you each have just the one. When you employ yours, the other guy is distracted from his offense and has to use most of his still & attention to evade, but can also use his tool to parry. But the tool is better at attacking than it is at parrying.
If you’ve ever watched a good staged swordfight and really considered how this would work in reality, you can see the dilemma both parties face. The guy who gets the momentum on his side is totally in control whereas the guy playing catch-up had better do so very quickly or the game will be over badly. Boxing is a bit similar, except in boxing the match will last longer than one good landed punch. With a sword or a missile the match ends at the first solid contact.
The drag & beam maneuvers he describes are used to defeat long range missiles that you know are in flight towards you. They’re also classic anti-SAM tactics. The short range and quick time of flight of dogfight missiles don’t give those tactics time or space to work.
There are huge benefits to shooting first. Which means the guy with the longer ranged weapon (which includes the radar as well as the ordnance, plus the skill to employ them maximally) is in the catbird seat. Once you have ordnance in the air, the other guy will either know it’s coming and have to react, or not know it’s coming and explode, ideally before he launches anything autonomous at you. While he’s reacting he’s having to do things, like gimbal, beam, or even drag, that are inimical to his own attack.
This is also why we don’t fight one-on-one. Historically a limitation of fighter radar was that you can either scan the sky, or track a single target, but not both. IOW, you go totally tunnel-visioned / blind as soon as you prepare to shoot, and for quite a while longer if the missile is a radar guided type. The blind duration is far far longer than is comfortable or safe if the enemy has anything on the ball.
Conversely, if there are several fighters cooperating, the shooters can (more) safely go blind while the followers keep at least some track of the whole scenario and can direct a tactical retreat AKA drag if the situation starts falling apart.
By my era, the 1980s, we had some degree of track-while-scan radars which could keep at least a partial big picture while also tracking a target (or a couple/few targets) while guiding ordnance to it/them. Now your tunnel vision expanded to seeing though a scuba mask, not a soda straw.
Later advances, like the datalink mentioned in the article are past my time but offer the promise of everybody sharing a single coherent composite picture derived from all the sensors on all the platforms. The advantage in clarity is obvious. Being overwhelmed by tactical complexity is a risk. It takes time for multiple pilots to sort out who’s going to do what to whom.
Anti-missile missiles:
Not yet. There is a fairly new thing called MALD, Miniature Air Launched Decoy. The idea is to tow a small (1 foot long) gizmo on a long wire which has jamming electronics to look bigger than the towing aircraft. So the enemy missiles track, hit, and blow up the decoy, not you. Ideally you can carry a few of these since each one only decoys a single hostile shot before being destroyed.
Another neat coming thing is laser IR countermeasures. A small laser is fired at incoming IR missiles. It doesn’t destroy them, but the crazy laser lightshow confuses the missile seeker until it loses track of the target aircraft. It then just flies a straight line until it falls from the sky. These are installed now on bomber and transport sized aircraft and are now being miniaturized for use on fighters & helicopters.
The good news is the laser has lots and lots of shots; practically speaking it doesn’t run out of ammo. The bad news is it’s only effective against IR missiles, and it’s very short range. If the laser works, you live. If not, you’re dead about a second later. So it takes a certain level of trust in the laser to ignore incoming IR missiles and press you own attack vice trying to evade them via maneuver, thereby abandoning your own attack.
Other than those inventions, it’s chaff for defeating radar missiles and flares for defeating IR. Neither of which worked all that well in my era and probably hardly work at all any more. Missiles have gotten a lot smarter. As well you only carry so much on board. The supply is real finite compared to the need in a serious melee.
Last of all there’s stealth and jamming (ECM in the argot). Jamming is a real technological cat and mouse game. The US has bet the farm on stealth. I’m not competent to offer an opinion on it’s effectiveness either now or 15 years from now.
That’s enough for now.
