Sensei (Japanese: ヤマモト, Yamamoto) is a Yellow Comet CO. A former paratrooper rumored to have been quite the CO in his day. Sensei possesses powerful infantry, superior firepower for Battle Helicopters, and increased movement range for transport units (Lander, APC, Transport Helicopter, and Black Boat), although his naval units have weaker attacks. He was also Kanbei's teacher, as was stated in Advance Wars 2: Black Hole Rising. During Advance Wars: Dual Strike, he joins the allied nations in Omega Land, along with another one of his students, Grimm.

Final Battle

"Whoa, nelly! Look at the size of that..."

(with Grimm)

Sensei: "Ah, Grimm, my old disciple. You've grown quite a bit during these battles... If you agree to train the rest of these rookies, I can finally die happy... If the battle ends poorly, you must escape! I can't outlive my finest student!"

Grimm: "Escape? Gwar har har har har! Sensei, we still need you back home! If you die on us, we're in big trouble! You're going home if I have to pick you up and carry you!"


"I might retire soon... I wonder how my 401k is doing."

(With Hachi)

Hachi: "Shop till you drop! Or until I drop you!"
Sensei: "Ha ha ha! You're such the businessman!"


Sensei's CO powers allow him to easily outnumber his opponents, aside from Hachi, the only CO able to keep up with Sensei in unit count.

Like Hachi, his power allows him to acquire more units, even if he does not control any factories. This can help the player out a lot on pre-deployed maps, where the player would otherwise not be able to build any more units.

In competitive play, Sensei is one of the very best CO's. This is because a high unit count is crucial to victory, as having a lot of Infantry and Mech units lets you protect your other units. If your Super CO Power spawns 10 9HP Mechs, that's essentially a 27,000G value. You can combine your Mechs to liquidate them into money.

Sensei's powers are practically free since Infantry and Mech units have an abnormally high charge rate. You can use the units spawned from your powers as fuel to use your powers again.


Hachi: Grizzled Vets; 2 stars, 100%

Grimm: Rolling thunder; 1 star, 105%

Von Bolt: 90%
