Wikipedia There is more information available on this subject at Call sign on the English Wikipedia.

The concept of a "Call Sign" has existed for almost as long as there has been aviation, from the Pilots of Earth's World Wars to modern Pelican pilots.


A call sign is a nickname adopted by a military pilot for use in name tags, planes and radio conversations. Though strictly unofficial, these names are adopted almost like a second name for the person they are attached to and thus, they are usually given by other pilots or coworkers. Each name varies and the reasons they are given vary as well.

Other types of soldiers also adopt call signs, depending on the circumstances. Most often, soldiers are given the name of their unit and a numerical position.[1] The leader of a unit will have the unit's name followed by the word "Actual".[2]

The Captain of a UNSC Starship is referred to by the name of the ship, followed by "Actual".[2]
