Zelazny explains that they were outfitted with experimental mechanical augmentations by Belltower, and had implanted with a neural hub that could manipulate memory centers in the brain, effectively controlling what they could and could not remember. After a couple of operations, Zelazny started to experience memory shifts, remembering bits and fragments of past missions, slowly realizing that they could not have been logically orchestrated by the government.
Eventually he found out that he and his peers were used by the corrupt officials in the American and Chinese governments. He confronted the project director, and had him disconnect Zelazny's and his colleagues' hubs. Going through the director's contacts, Zelazny found the list of the corrupt people that used him and his men, then proceeded to hunt them down, seeing it as justice.
