Personnel repulsorlift platforms were used in urban environments such as Coruscant and Nar Shaddaa to transport personnel between locations within the city. They were often used by crimelords for transport of the henchmen, and would sometimes serve as the base of ranged assaults.
Kyle Katarn was attacked by some of Reelo Baruk's thugs on Nar Shaddaa. He killed the thugs and used the platform himself to get access to a new location. Years later, his apprentice Jaden Korr would have a similar experience on Coruscant, as he was fired upon by a Rodian thug from such a platform.
