What is the name of Obi-Wan Kenobi’s clone battalion?

The story behind the answer

Obi-Wan Kenobi regularly commands the orange-marked unit led by Commander Cody (CC-2224) throughout the Clone Wars—seen at Geonosis, Ryloth, and notably Utapau, where Cody infamously executes Order 66 against him. Their armor markings and Cody’s close partnership with Obi-Wan make this pairing distinctive in both The Clone Wars series and Revenge of the Sith.

Don’t confuse it with the 501st, “Vader’s Fist,” primarily under Anakin Skywalker and Captain Rex; the 41st Elite, green-camouflaged under Commander Gree serving Luminara Unduli and later Yoda on Kashyyyk; or the 327th Star Corps, yellow-marked under Commander Bly and Aayla Secura on Felucia. The Cody–Kenobi connection is the giveaway.
