What is an "elevation adjustment" used for?

• A. Changing the bullet type
• B. Adjusting aim vertically
• C. Modifying the scope settings
• D. Estimating wind speed

Answer: (B)

An elevation adjustment is specifically used for adjusting aim vertically. This adjustment is crucial when shooting at targets at various distances, as the bullet's trajectory is affected by gravity. When a sniper must account for distance, the aim will need to be elevated to ensure that the projectile compensates for the drop over that distance. This adjustment is made using the scope's elevation turret, allowing snipers to precisely align their rifles based on the known distance to the target and the corresponding bullet drop.

The other options don't relate directly to vertical aim adjustments. Changing the bullet type may impact the overall performance and trajectory but does not affect the scope's elevation settings. Modifying the scope settings also encompasses a broader range of adjustments, including windage. Estimating wind speed, while essential to shooting, pertains to horizontal adjustments rather than vertical aim changes. Therefore, vertical adjustments are primarily accomplished through elevation adjustments, making it the correct answer in this context.
