This is coolbert:
Even in the aftermath of the Kobani defeat the ISIL onslaught continues.
From DEBKAfile the Kurdish city of Irbil [Er-beel] now in danger.
"18 Feb. Islamic State launches major offensive on Kurdish capital defenses"
"Forces of the Islamic State in Iraq and the Levant have embarked on a major assault to breach the security belt defending the Iraqi Kurdish Republic's capital Irbil and reached within 45 km of the city. International coalition aircraft in the area are unable to strike ISIS units because the two sides are in close-proximity combat on the ground. DEBKAfile: That the Islamists were able to mass forces so close to the Kurdish capital attests to the inefficacy of the US-Jordanian-UAR air offensive against the invaders."
Hugging tactics!! A legacy from the Vietnam War. Close-air-support [CAS] unable to drop munitions! That space between the friendly and foe too small for accurate and safe bombing.
ISIL masters the basics quickly.
