In the 1982 Lebanon War where Israel invaded up to Beirut, Syria intervened on the side of Lebanon and the PLO forces residing there. Israeli jets shot down between 82 and 86 Syrian aircraft in aerial combat, without losses. A single Israeli A-4 Skyhawk and two helicopters were shot down by anti-aircraft fire and SAM missiles. This was the largest aerial combat battle of the jet age with over 150 fighters from both sides engaged. Syrian claims of aerial victories were met with skepticism even from their Soviet allies.
