I wouldn't say that. I would still want to use SCUDs, for a couple of reasons:
1: Their armor type and HP. Voltmortars, while fast, are pretty fragile. If they lose their stealth ability, they're going to be a lot more vulnerable to enemy attacks, since the stealth was what made them so nightmarish to face against; you had no idea if they were near your base or not. Infantry go down reaaaaaaallllly easily in this mod; every faction to my knowledge has a very strong anti-infantry unit in their arsenal (US Riot Troopers, Euro Alliance Snipers, Soviet Desolators and Eradicators (If China), a lot of the hero units, etc), and even the toughest of infantry struggles to stay alive when these infantry killers come into play.
Also, Voltmortars can still be run down if they're not deployed. I imagine that my idea of making them attack while undeployed would make them vulnerable to simply having vehicles run over your very expensive investment (unless Voltmortars are changed to not be crushed in general, not just when they're deployed. SCUDs, on the other hand can take a good amount of hits for an artillery unit IMO, and their armor type means that they won't quickly die to bullets, radiation, or whatever else Voltmortars will instantly die to (Flashbangs, poison, etc.).
2. Range and Damage. If Voltmortars get nerfed in stats, they're not going to be doing as much damage as a SCUD will, and they're certainly not going to be able to fire as far as a SCUD either. Voltmortars would be great if you're dealing with AA defenses (which can destroy SCUD missiles if you have enough), or if you want some long range guerrilla warfare (Voltmortars are fast, don't forget). Otherwise, if you're looking for a pure siege unit, I'd still use SCUDs simply because they fire from such a long distance and do a lot of damage.
Way I see it, Russia-exclusive, rebalanced Voltmortar+My proposed Russia-exclusive Tesla Trooper replacement will make Russia much stronger than it is now. Currently, people seem to complain that Russia doesn't really have much compared to the other two Soviet factions; China is this heavy, powerful, nuclear+EMP-happy juggernaut that crushes everyone that crosses them, and the Latin Confederation are capable of causing mayhem with their relatively quick/annoying units (Jaguar, Mortar Quads, Arsonists, etc.), while still having a lot of firepower and armor (Catastrophes are reasonably fast, can attack everything, and have a passenger fire port, which makes them more versatile. Buratinos aren't something you should scoff at either, since they're also good at taking down large groups of infantry and supporting your army in a push). I'm just throwing ideas out there that help Russia not be considered "weak" or "boring" or "slow to play", as a lot of people claim.
