I was the Dispatcher on duty. I had received a 10 [mile] out call from Aircraft X on company frequency. I also had CTAF radio on in the dispatch office. There was an aircraft making garbled and unreadable call that turned out to be Aircraft Y. Aircraft X had made multiple calls for a straight in final at 10; 5; 3; 1 miles and short final. I was looking out the window of the dispatch office and observed Aircraft X on an extremely short final less than 200 ft. over the local cemetery; and Aircraft Y that made an aggressive short approach which appeared to start abeam the numbers of the runway and descended on top of and into Aircraft X. From my view Aircraft X was definitely the lower aircraft on approach and had the right of way. Aircraft X made an evasive maneuver to avoid collision from Aircraft Y which appeared to be less than 10 ft. horizontal and vertically. Aircraft X continued approach without further incident and taxied for deplaning and shut down. Aircraft Y continued very close behind before making a decision to go around. Following the incident; Aircraft Y radio call became more clear and concise and exhibited unprofessional radio etiquette before circling around for landing. At this time Aircraft Z was repositioning from east to west ramp on the taxiway and Aircraft Y exited the runway and cutoff Aircraft Z who had to taxi into helipad parking to avoid and give way to Aircraft Y. Aircraft Y then taxied to the FBO on the east side of the field and shutdown. This was the end of my observation.
A Dispatcher at a non-towered airport reported a NMAC on short final and the aircraft that caused the NMAC cut off a different aircraft while taxiing.
