What I note is that Ugluk is directly responding to Grishnakh when he says:
"We are the fighting Uruk-hai! We slew the great warrior. We took the prisoners. We are the servants of Saruman the Wise, the White Hand: the Hand that gives us man's-flesh to eat. We came out of Isengard ..."
If any of these things did not apply to the Uruk-hai in general, and Grishnakh really was a Uruk-hai, then wouldn't he have objected to this usage? I find Grishnakh's lack of objection to this statement far more telling than his lack of insults with the words Uruk-hai.
It's also curious that 'fighting' is considered a qualifier for Uruk-hai. If the only Uruk-hai are that of isengard, then all Uruk-hai are 'fighting Uruk-hai' because both Ugluk's statement and those of the Uruk-hai at Helm's Deep (the only self-labeled Uruk-hai in the books) identify themselves as fighting. If Uruk-hai includes the Uruks of Mordor, then it seems odd that some of them don't fight. What does Appendix F say? That the word uruk was applied to the soldier Orcs of Mordor and Isengard. Do some of these Soldier Orcs hold down desk jobs, so that they do not fight? Are there older Uruk-hai, who are making a living off the Mordor Pension Plan so that they no longer have to fight? Is this why fighting is a qualifier? From what I have read the word fighting would not serve as a qualifier for either the Uruks or the Uruk-hai, as both breeds (if they are different breeds) are clearly bred for fighiting (i. e. to be soldiers).
Also interesting is the fact that neither 'Oghor' nor 'hai' are pure Black Speech words, but were clearly derived from 1st age Orcish languages. Sauron devised the Black Speech during the Dark Years, which Tolkien tells us occurred during the Second Age. From the UT narrative 'The Druedain' it becomes apparent that the Orcs of Beleriand referred to the Druedain of Doriath as Oghor-hai. Since Doriath no longer existed when Sauron devised his Black Speech, it is highly unlikely that his 'hai' preceded the usage in Orcish Oghor-hai. Therefore I would say that the term 'hai' did not spring from Mordor but from Orcish, and Saruman (or Sharkey as his boys called him) would be as free to apply it to his Uruks as Sauron would have been.
