Shooting Stars and Electric Sheep — Richard Alan Dickson

The elite troops of the Fifth Infantry Division lead every planetary invasion -- a proud tradition and centuries of success for the iron-fisted Empire. When one hardened veteran freezes in the field, Doctor Bill Morris races to find the seed to the man's impossible memories. If the enemy can infect and immobilize even its elite troops, the Empire's galactic dominance may soon come to an abrupt end.
