Unit 5101, Shaldag is the Israeli Air force’s Tier 1 commando unit and is considered to be one of the most elite units in the IDF. 

The unit’s mission is to deploy undetected into combat and hostile environments to conduct special reconnaissance, establish assault zones or airfields, while simultaneously conducting air traffic control and commando actions. 

Shaldag helps the Israeli Airforce strike its targets from the air. Unit members speak the IAF's language and transmit precise target coordinates to fighter jets and attack helicopters.

Most of Shaldags operations are highly classified and not known to the public. 
The achievements of the unit are numerous, dramatic, and hidden behind a tight veil of official secrecy.
