Also, what the heck are the 'Guardians of Orthanc'? Unless you mean normal Uruk's ofc

Edit: Actually, Tolkien Gateway mentions 'Trolls in Isengard' but it appears as if a Rohirrim askes him about said trolls, but I'm sure that as a random warrior/citizen of Rohan, that hasn't ever ventured beyond perhaps Gondor or the Wold, wouldn't know what a troll looked like, and as the Uruk's were of great stature, they would have thought of them as giants, or the 'trolls' he had hard stories of from lands east and north There were no trolls in Isengard. The piece on Tolkien Gateway is under the In Video Games section, and is non-canon.

Guardians of Orthanc, while I guess OP is basing them on the Total War mods, are in fact canon in some respect. There were men who guarded the gates of Isengard (Saruman did not trust his Orcs), but we aren't told if they were a special unit. It's possible they were.

However, several Isengard units that should probably be added first due to higher relevance include the longbowmen, the half-orc warriors, dunlending horsemen, half-orc spies, and orc-men axemen.

Ithilion, Discussions Moderator (Auta i lómë) Longboworcs right? And the horsemen for Dunland...? Why should isengard get spies if there are no other factions with spies?
