Shotgun - Shotty Jockey

Close assault

Machine guns and shotguns aren't precision shooting weapons, so there's less a sense of mastery for using them. Marksman and gunslinger aren't really terms specific to a type of weapon by the way, they just refer to skilled shooters. But when you think of skilled shooters you think of people who can shoot with great accuracy, like a sniper or a hunter, or an impressive duelist who would use a pistol, hence why marksman and gunslinger have connotations for those types of weapons.

But if you want a name for a SWAT-esque operator then something like "Door-kicker" or "Vanguard" if they're meant to be an aggressive type, or maybe "Sweeper" if they're a supporting type (as is more typical of machine guns, which are mainly used for suppressing fire).

And they are even more limited when it comes to regular shot. So eager to jump down somebody's throat you make an ass out of yourself.
