This is the standard fall computer he has linked with that can see through his eyes.

This series has outstanding character development, a solid and well thought out overall plot line, and good story resolution in each book. The two things that really make the series the top of its genre are the interaction between the computer and the hero, and the realism of the situation. The interaction is a delicate balance that the authors perform magically. If the computer (Center) contributes too much, then the hero has too much of an edge, he doesn't have to try, and the story becomes boring. Without the computer, the hero is just this god like superhuman character that can do no wrong. The computer assistance makes Raj identifiable to the reader, even after he overcomes overwhelming odds to defeat the enemy. The realism comes from the fact that Raj is based on the life of a real person. The whole story is very similar to the story of Byzantine General Belisarius who conquered most of the Mediterranean world for his Emperor after the fall of the Western Roman Empire. That makes it very believable. The characters are very real. Their actions really happened a millenium and a half ago.

This is a must read for any fan of military fiction or empire building.
