As this particular type of weapon (The MAAWS/Carl G and recoilless rifles in general) does have a much louder, deeper, and more distinct sound profile than is currently represented in arma, I have personally concluded that this does negatively affect gameplay; anti-tank weapons are not quiet, nor do they sound like small arms. They are loud and obvious, and any antitank weapon that isn't lound and obvious negatively affects gameplay by making it more difficult to detect than reasonable
