I found an interest thing about Stukov in the Wikia:
Unlike DuGalle however, Stukov spent most of his military career in top-secret research rather than in actual combat, constantly striving to push the limit of conventional technology and physical theory to increase the effectiveness of UPL troops in warfare. His views on the subject were considered "unconventional."
Stukov was an "top-secret military" this demonstrate FINALY he was a "Ghost" (maybe the UED Ghost are called in other way in the Earth, but in BW they called Ghost for convention, like Primal Zergling and Primal Ultralisk, they are called Zergling and Ultralisk but they don't are realy Zergling or Ultralisk, but strains very similar to they)
This don t demondtrate nothing. An infestation is an infestation, Stukov don t became brainless because he have psionic power, Kaloth only made him the power of corruption and to control Others infested
I think the infestation of Stukov is unreversable, the Nanites can give a temporary cure, and not a permamently cure, I think this is the reason because the Protoss don't use this cure in Heaven, because is temporary.
Narud don t infested Stukov, he never comand zerg in HotS only terran and taldarim is command by Narud and he say the Zerg now is useless, and Stukov Said: I was betreyal and killer, launch in the Space, captureb by ZERG, resusitated and infestated, curated, tranfered at Moebius For study Protoss cure but they experimented. Narud don t infested Stukov, only made experiments in him
Stukov was infested by Kaloth, not by experiment of Confederation like Morik, the Infested Terran created by experiment of Confederation is called "Mutate" and they maintein the mentality sanity, the Zerg infestation transform you a decerebrate slave if you don't have a grat psionic power, Stukov was resuscitated by Kaloth's cells and later infested.
Stukov is dead with military suit, then the Kaloth's Zerg found the corpse of Stukov WITH the military suit and he was infested. Later Raynor disinfest him and I think the Zerg don't change clothes, so he have militaqry suit, then Stukov was carried in the Moebius and they start to do experiments with him. So he NEVER used the Ghost suit.
GN, I prefer to use the model with rifle beceuse in Resurection IV he was a hero with attack and Ghost ability and in the end of mission Stukov have a role how hero, but made him a Civilian hero is useless :S
Yhea I think to Stukov have psionic power, in SC1 exist the model of Civilian, the Blizzard can use them if Stukov don't is a Ghost, but they decided to use Ghost. And in Resurection IV in the end Stukov became a Hero with ATTACK, anche Ghost ability.
Well he was a Ghost and I will use this model for the other missions, and I think to add near of the Cocoon of Stukov a corpse of a Ghost with rifle and when he will be disinfested I remove the doodad of rifle with triggers and wuolah, Stukov get the rifle from the dead Ghost near of him
