The Hired Gun is a Career from the Edge of the Empire Core Rulebook.
When it comes to fighting, the Hired Gun is at the forefront. He’s less of an independent operator than the Bounty Hunter, preferring to have a defined mission, and objective to achieve, and some credits to spend when the job is done. Hired Guns are muscle and meant to defend or attack as the situation requires. They deal damage or protect others for credits, and this makes them simple and sometimes refreshingly direct.
Captain Panaka, Zam Wesell, and Greedo are all examples of Hired Guns in Star Wars.
