This is a role that is largely fulfilled by the squad's automatic rifleman. And wastegate is right - one target one shot - spraying and praying is not great for the locals or collateral damage control. I suppose that if a soldier finds himself in a situation where he needs to be firing 30+ rounds in a short period of time he should consider retreating to find some buddies.
