Clone Corps and Non-Citizen Warriors

One obvious one I'm sure simply slipped the Beast's mind is Timothy
Zahn's
Cobra. While Zahn ducks a lot of the psychoanalysis by making them
hardwired implants which actually override a soldier's conscious
reflexes,
there's no doubt the novel points a finger at the misunderstandings
arising
from combat reflexes in a peacetime setting. Zahn then goes on to give
the
soldiers a sort of Gulf War syndrome (painful chronic illnesses due to
wartime modifications) and then makes an argument for why Cobra warriors
are
still more valuable than comparably armed soldiers.

But now we're talking about training, conditioning, and treatment of
relatively valuable soldiers. Anyone have a take on Mr. Barclay's
original
topic which is a corps of warriors which you consider low-value or would
rather dispose of than reintegrate ? I think he was talking about hordes
of
clones, but could equally apply to troops you freeze between battles
rather
than granting R&R. These could be berserkers, non-humans, non-sentients,
automata, or just grossly abused citizens.

Just to spin another layer of OT, a friend raves about a book which he
read,
but doesn't know title or author. The story is about the personality of
a
soldier. The personality is backed up at the end of each successful
battle
or campaign, then reanimated for the next fight. His memory, as it
builds,
is a continuous stream of battles. Curiously enough, the author includes
bits like his contemporaries/peers who often fight the same battles or
against him in the same battles, but have different memories based on
whether they survived that battle or whether their side won. I like the
sound of the book, but obviously don't know how to find it. Anyone else
read this one ?
