Guys,
Rather than complaining about going against hordes I think they are fun and challenging to counter against. Bruv, Joker etc. all great fellows that know how to make the most of having their respective hordes. I salute them. 
On the other hand, what are some techniques and tactics one can use in defending a base from a horde once it is upon you?
Thanks for sharing,
Slade
Personally, I have loads of fun flying against the hordes...
But, to be honest, I make no effort to "counter" them, or to defend bases from them (although it probably appears that I am).
I'm simply out to shoot down as many of them as I can, and do my best to live and to land my kills. If I can do that, I'm generally having a great time. I seek out situations like this.
The way I handle them is like this... I lift the best plane in the game (F4U-1A, or maybe an F4U-4) and head out to the swarm. I lift from a base that's not under attack, climb on my way to the base being attacked, and level out to head in at 10-12k. Once on the scene, I "hunt" perpendicularly to the flow of traffic, and skirt the edges looking for stragglers. If a base is being attacked from the south, I'm going to make sure I do my fighting in an east/west manner, so that I'm not likely to get dragged into a swarm.
Ideally, I move in, get the attention of a "red" pilot or two, and get them to follow me to one side or the other. Once I'm out of icon range of the main thoroughfare I kill the guys chasing me. Rinse, wash, repeat.
Variations of this strategy will find me loitering near the outskirts of their base, or the one my country is defending. I'll also shift altitudes based on what the opposing team is doing, number of planes, etc. I don't like to be too much lower or higher than them, because it detracts from my ability to draw singles, doubles, or triples away from the swarm. If you look like you have control of the sky, they won't follow you... If you look too vulnerable, you'll probably have 15-20 of them on you at the same time...
I find it works best to be 1000-2000 feet below them, move into icon range just far enough to lure an attacker or two, and then move back out of icon range.
I don't fly with a wingman, and if I do, I don't actually fight with one as a "team".
What does work well though is to have a partner who flies near you, and allows you to fight on your own (without his assistance). If I'm fighting, his job is to stay between me and the swarm, and head off anyone who tries to come out and help my opponent. I'll generally "switch off" with a partner like this... I protect his fight, and then he protects mine. We'll let each other die in a fight like this; that's ok, because the fights are "fair" 1v1's. In a 1v2 or more, it's ok for the partner to join in. The "partner" scenario works very well from an SA point of view as well. We're constantly updating each other on what's going on around us, or which compass direction the "fighter" should try to drag the fight (i.e. "you guys are getting to close to the main stream of traffic; you'd better shift your fight to the east a bit...). Flying like this is tough, because you aren't just reacting to your opponent if you're also trying to drift the fight in one direction or another.
Fights against the swarm are some of the best the game has to offer, IMO. I can almost always shift from one 1v1 or 1v2 to another, until my gas and ammo are depleted. I then rtb, and do it again. Some nights are tougher, to be sure, but I certainly cannot complain that I can't find any fights, or 1v1's, or whatever, because I just go out and make them happen...
