Be careful with this one: you're "cherry picking" rulesets to prove your argument. You mention "domains" so you're obviously taking the stance that the rules represented the reality of the time, rather than the latest version of the rules "retconning" the past; ok. I'd have to go back to my old books to be sure, but I think that the Magic x 100 meter range for Spirit services is new to SR4. Besides that, I believe in any edition a Magician can Astrally Project to a location, summon a spirit there (matched to that location's domain) and command it from Astral Space.
Actually in this particular case i'm not domains is something that spirits lost in 4th because of the rising magtical level and a better understanding of magic so says the 4th edition books. If memory servers the 100 x magic level has been around since at least 3rd edition. Astrally projecting is one chink in the theory that I will concede however if a mage is astrally projecting to guiode the attack their not summoning more spirits as others have suggested. So there is a limited amount of resources that can be sent out on this attacks, finite number of magical resources and whatnot. WOuldn't be a huge deterance given astral travel speeds but it is a limiting factor considering the multitudes of military assets and targets scattered throughout the country.
Additionally from another thread, as to manifesting spirits, stick-n-shock.
