Scans for hostile units
Just like the Orca's rechargeable Pulse scan ability, these scanners are capable of detecting even stealth units. However, the device needs at least ten seconds to transmit the signal, and the time can be used by the enemy to destroy the scanner, which has no way to defend itself.
During the Second Nod Reunification War, five of these scanners were deployed near Black Hand leader Marcion's headquarters in Australia, whose forces have found a way to circumvent the scanners. LEGION's forces, however, had to resort to destroying them to prevent detection during the Persuasion of Marcion.
