What setting must the DOS be on for range estimation with the Leupold Mark 4?

• A. 2x
• B. 5x
• C. 10x
• D. 15x

Answer: (C)

The appropriate setting for range estimation with the Leupold Mark 4 scope is 10x. This magnification is commonly used in sniper operations because it provides a good balance between detail and field of view. At 10x magnification, the sniper can accurately identify target features while still having a sufficient field of view to maintain situational awareness and observe any potential threats or changes in the environment.

Using the scope at 10x magnification allows the sniper to effectively utilize the reticle or ballistic interpolation for range estimation. This is particularly important for calculating holdover and making accurate shots at varying distances. Higher magnification could provide a more detailed view but may reduce the field of view and make it more difficult to track moving targets or assess the overall landscape. Conversely, lower magnification settings do not provide enough clarity for precise distance measurements, which are crucial for effective shooting.

Thus, the 10x setting strikes the optimal balance needed for accurate range estimation during sniper operations.
