For a number of decades, among the most prevalent training media in the military has been Tactical Engagement
Simulation (TES) training. TES has allowed troops to train for practical missions in highly realistic combat
environments without the associated risks involved with live weaponry and munitions. This has been possible because
current TES has relied largely upon the Multiple Integrated Laser Engagement System (MILES) and similar systems for
a number of years for direct-fire weapons, using a laser to pair the shooter to the potential target(s). Emerging systems,
on the other hand, will use a pairing method called geometric pairing (geo-pairing), which uses a set of data about both
the shooter and target, such as locations, weapon orientations, velocities, and weapon projectile velocities, nearby terrain
to resolve an engagement. A previous paper  introduces various potential sources of error for a geo-pairing solution.
This paper goes into greater depth regarding the impact of errors that originate within initial velocity errors, beginning
with a short introduction into the TES system (TESS). The next section will explain the modeling characteristics of the
projectile motion followed by a mathematical analysis illustrating the impacts of errors related to those characteristics.
A summary and conclusion containing recommendations will close this paper.
