What is the quadrant elevation (QE) range of the M777A2?

The quadrant elevation (QE) range of the M777A2 Howitzer is vital for understanding its operational capabilities. The M777A2 is designed to fire accurately at a wide range of elevations, which are measured in mils. The correct range of -43 to 1275 mils indicates that the howitzer can adjust for very low angles of fire, which can be crucial in specific combat scenarios, as well as for a considerable elevation to target distant threats effectively.

This capability allows for a greater variety of targeting options, ensuring that the weapon system can engage effectively in different terrains and against various types of targets. The QE range ensures that gun crews can efficiently set their armament to match the necessary firing solutions, contributing to the artillery's overall effectiveness in support of ground forces.

The other ranges might suggest capabilities that are either insufficient or exceed the actual design parameters of the M777A2, which is why they are not applicable.
