I figured them being less simulacra and more like Fate's Heroic Spirits; actually sort of the soul of the person in question but not quite. Except that, you know, none of the supernatural oomph those guys have, they are really only about as powerful as they were in life or as much as Doug can support with his magic.
I also figure that the song is more efficient when calling up groups of otherwise ordinary guys. Utter badasses, possibly, especially if he manages to get a recording of a bunch of SEALs or SAS troopers since that would then allow him to pull on those units' history, but no empowerment beyond good training. Because then the song is not best used as a similar trick to 'With a Little Help From My Friends,' but as 'summon military unit.'
And of course, most likely a power hog song by most standards. Because even just E company 2/506th PIR would under the rules I proposed easily be something like 400 guys he could in theory call upon. And unless the opposition is breaking out the modern armoured vehicles, they'll be equipped to handle almost anything.
