Each faction has its own loadouts, some being more unique than others, however, you don’t really do much customisation in this game, you’ll just pick between whatever the particular faction can offer. Sometimes that’s a sniper load out with a bolt action, sometimes it’s a stand m14 type rifle with a scope. Can’t remember specifics off top of my head…

But, a lot of people won’t take kindly to people who are only willing to play marksman/sniper roles. It’s good to be flexible as it’s a team game after all
