The tactic was used sparsely but that is what it made valuable. The Islamic State fighters fell for it again and again. One wave of reserves after the other was sucked into observable positions and destroyed. During four and a half month some 600 air-strikes killed about 1,400 Islamic State fighters around Kobani including high ranking commanders, important scholars and many foreigners. 600 air strikes during such a long time frame is a low number. During the 2006 Lebanon war the Israeli air force flew about as many strikes per day. But that low number deceived the Islamic State and let it believe that it could win a fight which in reality turned out to be a meat grinder.

I thought this was an interesting perspective. I recall the War Nerd arguing that the US was hoping that Kobani would fall.
