Motion tracker (Earth-5875)

"Alright, Hicks, Hudson, use your motion trackers."

- - Lieutenant Scott Gorman

The motion tracker is an equipment used by the UNSC and the Covenant. Aside from being a common field equipment to the UNSC Marine Corps, it is built into the HUDs of many combat suits, such as the HRUNTING/YGGDRASIL Mark I ADS, the MJOLNIR Powered Assault Armor, and the sangheili combat harness. The tracker indicates to the user about their allies and enemies.

Overview
"Movement. Signal's clean. Range: twenty meters... Eighteen... Seventeen meters... Fifteen meters... Thirteen meters. Man, this is a big fucking signal."

- - Private First Class William Hudson

The motion tracker is represented by half a circle with a central dot, which indicates the location of the user. It displays the individual allies, enemies, and anything that moves in the environment. The dot size depends on the size of what is being scanned: for example, normal infantry is represented by normal sized dots, while smaller life forms, such as fishes, rats, cats, and even Facehuggers, are represented by smaller dots. Larger dots represent either vehicles or large infantry, such as mgalekgolo and xenomorph Praetorians.
