No, combat styles are split between force and tech. So a "jedi" or "sith" character can use any force combat style (From the more wizard ones, to tank ones).
Meanwhile, Bounty Hunters, Smugglers, Troopers and Operatives can all use each others advanced classes. So a bounty hunter can use a rifle or carbine, finally---while a smuggler can use the BH pistol stuff.
It really should have launched like this. I love the BH class design, but it always bugged me that the fucking Smuggler/operatives could use rifles/carbines but the BH never got the option to.
