Fortunately, Kanga MDMs were stupid compared to human weapons, and these had to make a half-dozen "downstream" translations to reach Sentinel. If tracking problems afflicted BatDiv Ninety-Two's defenses, they would also force the Kangas' missiles to rely almost entirely on their homing systems, and they were bleeding energy all the way down-gradient. That lost energy would form a "bow-wave," inducing myopia in their onboard tracking systems guaranteed to degrade their accuracy dramatically. It would have required the full efforts of all three Trollheims to guarantee saturation of Sentinel's defenses at this range, and that was why Santander was certain no Troll tactician had ordered this launch.

"Interdiction fields active," Miyagi reported, and she nodded. The last-ditch interdiction fields, like all active defenses, worked best against the longer flight times of missiles chasing from astern. They were simple in concept: focused directional energy fields projected into the paths of incoming attackers. A Guardian-class dreadnought could put out ten of them, but each was relatively tiny. The trick was to drop them exactly into the attacking weapons' line of flight, and when flight time was short and gunnery's lock was weak, it was almost as much a matter of experience and intuition as computer prediction... .

Three decoys vanished, and four incoming missiles went with them. Two more MDMs ran headlong into interdiction fields and disappeared into infinity. The remaining pair whizzed past Sentinel at almost the same instant-clean misses, with absolutely no chance of tracking back around at this velocity and translation gradient-and Commodore Josephine Santander realized she had been holding her breath only when she let it out. A third of the enemy's after firepower had just been expended for absolutely no result!
