The planet Osarian's military space force was known as Osarian First-Force. This force, which contained Z-95 Headhunters, was led in 25 ABY by the Rodian mercenary Captain Grappa. Before the Osarian leaders, Leia Organa Solo and Mara Jade Skywalker came to parley with Nom Anor; Grappa dispatched six Headhunters to "escort" the Jade Sabre to Osarian, but Jedi Knight Wurth Skidder eliminated two of the four Headhunters.
