In many fantasy universes, necromancers are feared. They are regarded as generally evil, forces of chaos, and defiers of the natural order.
Now consider a world like our own, where a select few use not magic but science to raise the dead. Obviously some are 'evil', rasing armies of the dead to ead attacks upon the world, but some would be 'good', trying to use their newfound 'powers' to cleanse the world of darkness. Hell, there might even be some playing a role similar to Garth Nix's Abhorsen, a style of necromancer who lays the dead to rest.
My question is this: Would the use of a scientific necromancer be viable in modern warfare? Consider that:
The dead will follow the necromancer's will, but only by force. They use some kind of mind control drug-collar-thing.
Raising the dead requires a laboratory to do. It cannot simply be done on the battlfield.
Raising the dead takes a vast ammount of energy (Say 1 minute of the machines running uses the energy generated by 1 reactor in a nuclear power plant in the same time).
Due to the energy taken, only 1 necromancer can work in a location at a time. No, it doesn't make much sense, but just roll with it.
Just like regular zombies, you kill the raised by destroying the brain. Hence, the bodies must be fresh when delivered, as the brain decomposes rapidly.
Bearing this in mind, would a modern army want to use these necromancers? If so, to what extent? And if not, what sort of changes would the necromancers have to make to their methods to make them viable?
Raising the dead takes a vast amount of energy
how many soldiers per batch on average, and how long does each batch take? That will greatly impact the cost. $\endgroup$
