Sensei (Japanese: ヤマモト, Yamamoto) is a Yellow Comet CO. 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.


Sensei is an elderly paratrooper wearing an orange jumpsuit and a brown helmet with aviator goggles. He has a parachute pack attached to the front of his body, held in place by many buckles. Sensei also wears brown shoes and has some sort of green insignia on his collar.


Sensei is generally very laid-back and actually prefers not to fight in combat. He gives plently of combat advice to the younger COs, advice that he gathered up from long years of fighting. Sensei has a good sense of humor and likes to relax. However, this is not to say that Sensei is lazy. If pressured to do so, Sensei will fight only to defend people he cares about. Despite the reputation he has garnered as an "unbeatable" CO, Sensei appreciates it quite modestly. Sensei is not fond of disrespectful opponents who underestimate him because of his age, or opponents who disregard his advice. Adder is perhaps the most notable example of this.

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!"


A mech spammer by nature, Sensei has a reputation for being very difficult and very annoying. For most the things that his infantry can't hit, he has extremely powerful Battle Copters to boot. 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. Sensei has the capability to overwhelm opponents with mass swarms of infantry, and obscenely strong infantry at that. Having such strong infantry makes capturing cities much easier for him, and makes interrupting other captures easier.

Like Hachi, his power allows him to acquire more units even if he does not control any factories, allowing him to bypass the rules of the game. 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. Sensei's CO Power in Dual Strike is practically free since Infantry units have an abnormally high charge rate there. You can use the units spawned from it as fuel to use your powers again.

Due to specializing in only three units, Sensei is a rather one-dimensional CO. Anti-Airs can deal with his powerful infantry and battle copters, especially if they get the first strike. COs with defensive strengths, such as Kanbei and Sturm, can usually power through whatever kind of infantry storm Sensei players may be planning. In Advance Wars 2 specifically, Sensei's vehicle units have lower firepower, which may cause trouble for him in the early game when both players start building their first Tanks. Since his infantry and battle copters have normal defense, whatever kind of units that can OHKO battle copters and infantry normally will still apply to Sensei as well.

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. This allows Sensei to purchase the normally expensive units such as Neotanks or Bombers. However, Sensei has weaker firepower with naval units and vehicle units(only in Advance Wars 2).
