An optional upgrade of the Zone trooper and Zone raider armour, the scanner pack was a set of sophisticated sensors and scanning equipment that increases the armor's sight and weapon range capabilities as well as limited detection of active camouflage systems.
Although the brief description reads "detects stealth in a small radius," the detection range is comparable to—if not greater than that found on defensive structures such as Watchtowers, Guardian Cannons or AA Batteries. Combined with Zone Infantries' extreme resistance to tank cannons, crushing and Tiberium, as well as their excellent anti-armor capabilities, the ability to detect stealth just makes them even more dangerous against enemy vehicles of every type.
