What is the standard unit of measurement used in adjusting a weapon's sights?

The standard unit of measurement used in adjusting a weapon's sights is the Minute of Angle (MOA). MOA is particularly relevant in shooting because it allows shooters to make precise adjustments to their sights for accuracy at various distances. One MOA subtends an angle of approximately one inch at 100 yards, making it easier for shooters to calculate adjustments based on their distance to the target. This precision is crucial in a military context, where accuracy can significantly impact performance and mission outcomes.

Other units, such as millimeters, inches, or yards, lack the specific angular measurement useful for sight adjustments across varying distances. MOA provides a standardized method to communicate and execute these critical adjustments, ensuring consistency and accuracy in weapon handling and targeting.
