Exerpt from "Star Wars Battlefronts" ...

You can take the enemy head-on or pull back as your crew steps up and starts throwing heat. Or you can survey your surroundings, take advantage of a vacant turret, and blast the opposition to pieces. Or, possibly, issue a command for a member of your party to turret duty while the rest of you take up strategic formations. Delegating orders to your crew is as easy as pointing a crosshair at a spot, and if your trooper can physically get there, bam, that's it. ...
