Spyglass target designator

"Designed to complement other Allied weapons platforms, the Spyglass target designator (colloquially called the "target painter") relays targeting information to nearby Allied forces. By automatically interfacing with their weapons systems, the target painter makes other forces more accurate and deadly by compensating for wind direction, visibility, and more than 100 marginal factors--all of which add up. A Guardian Tank is unable to maintain the beam through the recoil of its main gun's firing sequence, so Guardian crews must coordinate well to decide which unit within the column is going to "cast the lure" (as Guardian technicians put it) while the others press the attack."
