@Melissia -
Mmm... granted. I suppose it's the question of 'Is AI life, true life?' If it walks, talks and looks human - is it human? Similarly, it's the Theseus's Ship Paradox - if you replace all the components of an object (Theseus's Ship), is it still the same ship?
So in this case, if the marine retains his memories, characteristics and ability to converse (Indicating a level of continued mental operation) is he 'alive'? Similarly, if all of this continues despite extensive reconstruction by cybernetics, is he truly the same marine?
To be honest, I do agree with you on the ambiguity of it, but,
IMHO, in this case I'd tentatively deem them resurrected, even if it isn't a perfect biological and independent resurrection. For instance, is a person on life support truly alive, even if they rely on the machine to exist - I suspect the answer to those questions are far more complicated than can be answered on an internetz forum dedicated to tiny plastic men
