You can get beat up badly by an AK hoard raid but doggone it can be quite exciting trying to stop them. 
No disrespect to the AKs—but let's be honest, they're notoriously known as one of the least strategically impactful squadrons in Aces High history. They put up a big red cloud, sure—but when the dust and smoke settle, it's rare to see them take a base or even make it back to land the sortie when flying as a group.
Now, don't get me wrong—AKs offer great wingmanship. Every single one of them is a pleasure to talk to. Nothing but respect on a personal level. But for the sheer number of AKs on the roster, all I ever seem to get in return... is high ENY.
Isn't that a damn shame?
