Here's the scenario I just thought of, and I need some clarification.
UPS shuttle has the Targeting Synchronizer upgrade and has an enemy ship locked.
Gamma Squadron Vet. Equipped with Homing Missiles uses the target lock provided by the UPS's tech upgrade to shoot at said enemy ship.
The text on Targeting Synchronizer includes "when a game effect instructs that ship to spend a target lock, it may spend your's instead"
Could the Gamma Squadron Vet use the target lock to reroll his attack dice, since Homing Missiles does not require you to spend the target lock? Or does the Gamma Vet have to actually own said target lock?
