TACPAD

The TACPAD is a piece of United Nations Space Command equipment. It is a hand-held tactical database system used for analyzing and displaying combat information. It is most often used by NCOs and pull up maps of the local area and display images. It might be related to a small hand-held computer, or "Data Pad".

One UNSC Marine stated: "How the foxtrot does it track anything? Whatever—I guess that’s why I carry an em eh five instead of a TACPAD." in reference to a Covenant Plasma Pistol's tracking feature. This comment indicates a TACPAD might also be used for "tracking" a target, but not for actually engaging it.
