If Milan's stated location is correct, the licence ratings may well be those in ICAO Annex 1. It is possible that Ukraine has not implemented EUROCONTROL ESARR 5 and has not transposed the relevant EU directive/regulation. If this is the case the choice of ratings would be limited to aerodrome control, approach control or approach radar control.
Whatever the licensing arrangements, nothing changes the basic principle that controlling aerodrome traffic is primarily done by looking out of the window.
