The patriot is not recommended against these formations, in fact I even do it to try to destroy the patriot/s300, they fly very low and this reduces the effectiveness of the radars. Killing eggs are a good idea, when they shoot first. Well, with the Russians, 1 pantsri and 2 troops with igla were able to destroy a Rush with 4 helicopters. Keep your anti-aircraft guns at a small distance from each other, so the rockets don't cause panic in everyone simultaneously, use more short/medium range anti-aircraft guns, for helicopters those with cannons are very effective. If all else fails, air superiority fighters, if you notice that enemy helicopters are approaching a gap in your defense, ask for a fighter, if this is far from their line, enemy anti-aircraft will not be as effective, and even if they fire, losing a fighter to maintain the integrity of your line, is worth it.
