Early in World War II, target range and bearing measurements were taken over a period of time and plotted manually on a chart. [14] The speed and course of the target could be computed using the distance the target traveled over an interval of time. During the latter part of World War II, the speed of the target could be measured using radar data.
1. Determine the slant range to the target. Assume that a range finder is available that determines that the target is exactly 300 meters distance. 2. Determine the elevation angle of the target. Assume that an angle measurement tool is used that measures the target to be at an angle of with respect to horizontal. 3.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
A blinking target or a target moving toward a selection area are examples of temporal targets. Similar to space, the distance to the target (i.e., temporal distance D t) and the width of the target (i.e., temporal width W t) can be defined for temporal targets as well. The temporal distance is the amount of time a person must wait for a target ...
One significant method for combat resolution entails determining the ratio of the attacking unit's attack strength versus the defending unit's defense strength. This method is used in many games; one of the earliest and more prominent games to use this system was the game Panzerblitz, which was a genre-defining game when it was published in 1970.

Firstly, estimating the distance to the target is critical at longer ranges, because the difference in the point of impact between 400 and 500 yd (460 m) is 25–32 in (depending on zero), in other words if the shooter estimates that the target is 400 yd away when it is in fact 500 yd away the shot will impact 25–32 in (635–813 mm) below ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
