To make adjustments in elevation or searching with the M240, what should the operator do?

To make adjustments in elevation or searching with the M240, moving the elbows closer together or farther apart is the correct approach. This action allows the operator to maintain stability and control over the weapon while adjusting its elevation. By manipulating the positioning of the elbows, the shooter can shift the angle of the weapon; bringing the elbows closer together typically elevates the muzzle while spreading them apart can lower it. This method is crucial during operation as it helps achieve the desired targeting without the need for mechanical adjustments, which may not be immediately available in the field.

Adjustments through body position, rear sight changes, or strap adjustments have different purposes and efficiencies but do not directly influence the elevation in the way that manipulating elbow positions does.
