Originally posted by DarthPlaguis12Barring Palpatine himself, Tarkin > ALL. This fact has been well established across a slew of difference sources(both Legends AND canon.) Regarding Thrawn: Rebels made it abundently clear that he was olbigated to follow Tarkin's orders as well. I posted the pertinent dialogue on the first page, but here it is again:
I'm guessing that's new canon as in legends the grand admirals we're above the grand moffsTarky is still bad ass
Thrawn: "It's exactly this moment I have been waiting for... To wipe [the Rebels] out!"
Tarkin: "I want you to capture their leadership."
Thrawn: "In such a battle it may not be possible to take prisoners..."
Tarkin: "Ah, but a man of your talents will manage. If we are to crush this Rebellion, we must make examples of its leaders."
Thrawn: "As you wish, Governor Tarkin..."

That said, not all Grand Moffs held an equal level of power/authority. Tarkin was very much an exception.
Originally posted by DarthPlaguis12Tarkin's authority spanned both political AND military venues. As mentioned, we already know that even Vader, the Inquisitors, and Grand Admiral Thrawn were obligated to follow Tarkin's orders, but there were a few other instances where his uncanny level of authority was depicted...
Moffs hold military power just as would a grand admiral
For example, it was Tarkin who promoted Arihnda Pryce from civilian status to the system Governor of Lothal(a promotion like this was unprecedented.) Mind you, in any other instance Governorships were appointed through the Imperial Palace's bureaucrats, but Tarkin bypassed them entirely and granted her the rank/title on a whim. This showcases his massive political/civilian power.
Soon thereafter, Tarkin had the Imperial Navy's high-council promote Thrawn from Commander to Commodore, and give him his own Star Destroyer to command(the Chimaera.) He also had them promote Eli Vanto from Ensign to Lieutenant-Commander. This showcases his massive military power as well.
Of course, this is all secondary to the fact that multiple sources confirm that Tarkin was the Empire's top dog, period...
So yeah...
