Any errors in range estimation are tactically irrelevant, as a well-aimed shot will hit the torso of the enemy soldier.

She sat hooked into her own sensors, studying them, taking in a steady trickle of data: range estimation, target probabilities, weapons status.

"At greater distances, the curvature will be much more apparent, and errors in aiming or in range estimation will be more pronounced."

During this phase students will become experts at engaging targets at unknown distances by way of range estimation and range cards.

The scope's reticle pattern is easy to use and makes range estimation quick and reasonably accurate without any mathematical calculations necessary.

The new IS cartridge had a flatter trajectory, and was therefore somewhat less critical of range estimation.

A light, fast bullet gives a flat trajectory, making range estimation less vital for accurate shot placement.

Some sights use a chevron or triangular pattern instead, to aid precision aiming and range estimation, and still others provide selectable pattern.

Further, binoculars designed for military usage may include a stadiametric reticle in one ocular in order to facilitate range estimation.

The Mil-dots serve two purposes, range estimation and trajectory correction.
