Obi-Wan Kenobi must lead the assault on Muunilinst. Anakin Skywalker commands the space forces.
It is the start of the Clone Wars and Master Yoda explains how Republic troops are fighting Separtist Army all over the galaxy. More neutral and Republic planets, including Mon Calamari, are starting an alliance with Separtist Leader Count Dooku. Then, the montage shows several war scenes including Mace Windu fighting against B2 Super Battle Droids, Luminara Unduli and Barriss Offee fighting together, Saesee Tiin leading a Jedi squadron against thousands of battle droids, clone trooper fighting on a planet and finally Obi-Wan Kenobi and Anakin Skywalker jumping from LAAT gunship into big battle.
Then scene cuts, to Supreme Chancellor's Senate Room, where Master Yoda and Obi-Wan Kenobi are talking with Senator Palpatine about the war on Muunilinst. Senator Palpatine told two Jedi that his good friend and Jedi Padawan Anakin Skywalker should lead the battle. Masters Yoda and Kenobi didn't agree because they thought Skywalker was too young for the mission. But on the end, Obi-Wan agreed because as Senator Palpatine said, Anakin's piloting skills were remarkable.

He watched them geting aboard their Republic Cruisers and wonders what would his master, Qui-Gon Jinn say about the Clone Wars.
