Stealth Tactical Aerial Reconnaissance Satellite

The Stealth Tactical Aerial Reconnaissance Satellite, or STARS for short, is a piece of equipment used by the UNSC during offensive combat operations.

Summary
STARS are baseball-sized satellites that orbit one hundred kilometers over combat situations to provide in-field unmanned tactical command and to relay mission results and statistics to the Office of Naval Intelligence post-mission. They are capable of mapping large areas and providing real time topographical intelligence.

Functions
STARS are extremely useful; they covertly relay communications, topography information, enemy locations, and allied locations and equipment positions to the HUD of allied units in range. Furthermore, channels like TEAMBIO are relayed across STARS. They also broadcast orders for individual units. STARS help the UNSC military coordinate even complex operations easily and under stealth conditions, where even COM chatter can give away unit positions.

Usage
They were first seen in use in the Battle of Pegasi Delta and the Battle of K7-49, and operated in conjunction with SPARTAN-III commandos.

However, as per Mendez, "Machines break", and STARS was accredited for the over 99% fatality rate of Beta Company in the Battle of Pegasi Delta, where STARS failed to recognize the looming presence of no less than seven Covenant Cruisers over the Covenant tritium factory there. This led to a massive Seraph plasma charge bombardment and pulse laser sterilization of the SPARTAN-IIIs.

It is unknown why there was such a critical failure of the STARS.
