CO Tier List & Synergies

Understanding which Commanding Officers (COs) excel in various situations and how they synergize with specific unit compositions is crucial for dominating the battlefield in Advance Wars. This detailed guide breaks down the current meta, offering actionable strategies for both new recruits and seasoned tacticians.

Tier Explanations

  • S-Tier: Dominant Forces - These COs possess abilities that consistently provide overwhelming advantages, often dictating the pace and strategy of a match. They are strong in almost any scenario.
  • A-Tier: Strong Contenders - Highly effective COs with powerful abilities that can turn the tide. They might have minor weaknesses or require specific strategies to maximize their potential but are always a solid choice.
  • B-Tier: Situational Specialists - These COs can be incredibly strong in the right hands or on specific maps, but their abilities might be less universally applicable or require more careful planning.
  • C-Tier: Niche Picks - While not inherently "bad," C-Tier COs often have abilities that are difficult to leverage effectively, are easily countered, or are simply outclassed by higher-tier options.

S-Tier COs & Synergies

Andy: The Balanced Tactician

Andy's strength lies in his incredible versatility and the ability to recover from setbacks. His CO Power, Hyper Repair, heals all his units by 2 HP, and his Super CO Power, Hyper Upgrade, heals by 5 HP and boosts all unit stats by 10% for one day. This makes him a formidable opponent in prolonged engagements.

  • Strategy: Andy excels in defensive-offensive play. Use his healing to keep your front lines healthy, allowing them to absorb more damage and maintain map control. His stat boost from Hyper Upgrade can be devastating for a decisive push or to repel a strong enemy assault.
  • Synergies:
    • Heavy Armor (Tanks, Medium Tanks, Anti-Air): Andy's healing significantly extends the lifespan of these expensive units, making your investment more worthwhile. A healed Medium Tank can often withstand an extra hit, turning the tide of a skirmish.
    • Artillery/Rockets: While not directly benefiting from the stat boost in the same way as direct combat units, keeping these support units healthy ensures continuous long-range pressure.
    • Infantry/Mechs: Healing these capture units allows them to secure properties more reliably, even under enemy fire, and maintain a presence on the front lines.
  • Actionable Steps:
    1. Early Game: Focus on capturing properties with Infantry and Mechs. Use your CO Power (Hyper Repair) to keep them healthy if they come under early pressure.
    2. Mid Game: Build a balanced force, prioritizing Tanks and Artillery. Save your Super CO Power (Hyper Upgrade) for a critical turn where you need to push through an enemy choke point or defend a key objective.
    3. Late Game: Continue to leverage Hyper Repair to maintain unit longevity. Use Hyper Upgrade to secure a final objective or break a stalemate.

Max: The Powerhouse

Max is the undisputed king of direct combat. His direct combat units (Tanks, Recon, Anti-Air, Mechs, Infantry) gain a 20% attack bonus, but his indirect combat units (Artillery, Rockets, Missiles) suffer a 10% attack penalty and reduced range. His CO Power, Max Force, boosts direct combat unit attack by 30% and movement by 1, while his Super CO Power, Max Blast, grants a 50% attack boost and +2 movement.

  • Strategy: Max demands an aggressive, direct combat approach. Overwhelm your opponent with powerful Tanks and Mechs. His CO Powers are excellent for breaking through enemy lines or quickly closing distances to engage.
  • Synergies:
    • Tanks (Light, Medium, Neo): These are Max's bread and butter. Their increased attack makes them incredibly efficient at destroying enemy units.
    • Recon/Anti-Air: While not as powerful as Tanks, their boosted attack makes them surprisingly effective in their roles, especially for quickly eliminating enemy Infantry or air units.
    • B-Copters: Max's air units also benefit from his direct combat bonus, making his B-Copters exceptionally dangerous for harassing ground units.
  • Actionable Steps:
    1. Early Game: Prioritize building Infantry and Mechs for capturing, but quickly transition into producing Tanks. Use Recons aggressively to scout and eliminate enemy Infantry.
    2. Mid Game: Build a core of Tanks and B-Copters. Avoid building Artillery or Rockets unless absolutely necessary for specific map layouts. Use Max Force to gain a decisive advantage in a key engagement.
    3. Late Game: Consolidate your direct combat units and use Max Blast to deliver a crushing blow, often leading to a swift victory. Focus on overwhelming key enemy units.

A-Tier COs & Synergies

Sami: The Infantry Queen

Sami specializes in Infantry and Mech units. Her Infantry and Mechs have a 20% attack bonus and capture properties twice as fast. Her CO Power, Double Time, boosts Infantry/Mech movement by 1 and attack by 30%. Her Super CO Power, Victory March, grants +2 movement and a 50% attack boost to Infantry/Mechs, and they can capture properties in a single turn.

  • Strategy: Sami excels at rapid property capture and overwhelming opponents with a flood of boosted ground units. She is particularly strong on maps with many properties or chokepoints that favor infantry.
  • Synergies:
    • Infantry/Mechs: This is obvious. Maximize their numbers. Use them to quickly secure income and then push aggressively.
    • APC/Transports: Essential for rapidly deploying Sami's powerful infantry across the map, especially on larger maps.
    • Anti-Air/Recon: While not boosted, these units can protect Sami's valuable infantry from air threats and scout ahead.
  • Actionable Steps:
    1. Early Game: Mass produce Infantry and Mechs. Focus on capturing as many properties as possible, as quickly as possible.
    2. Mid Game: Use Double Time to make a rapid push for central properties or to capture a key base. Support your infantry with a few Anti-Air or Recons to counter immediate threats.
    3. Late Game: With Victory March, you can capture an enemy HQ in a single turn if you manage to get an Infantry unit onto it, making her a potent rush CO. Alternatively, use the boosted movement and attack to break through a fortified position.

Grit: The Indirect Master

Grit is the antithesis of Max, specializing in indirect combat. His Artillery, Rockets, and Missiles gain a 20% attack bonus and +1 range. However, his direct combat units suffer a 20% attack penalty. His CO Power, Snipe Attack, boosts indirect unit attack by 30% and grants +1 range. His Super CO Power, Super Snipe, grants a 50% attack boost and +2 range.

  • Strategy: Grit plays a defensive, long-range game. Establish a strong defensive line with indirect units and use their extended range to chip away at the enemy from a safe distance.
  • Synergies:
    • Artillery/Rockets/Missiles: These are Grit's core units. Build them in numbers and position them strategically behind a defensive screen.
    • Tanks/Anti-Air: These units serve as a protective screen for your indirect units, absorbing damage and engaging any enemy units that get too close.
    • Recon: Crucial for scouting ahead and revealing enemy positions for your long-range bombardment.
  • Actionable Steps:
    1. Early Game: Capture properties with Infantry. Build a few Tanks or Anti-Air for initial defense, then start producing Artillery.
    2. Mid Game: Establish a defensive perimeter with Tanks and Anti-Air. Position your Artillery and Rockets behind them, using their extended range to harass the enemy. Use Snipe Attack to break through a fortified enemy position or clear a path.
    3. Late Game: Continue to expand your indirect fire power. Use Super Snipe to unleash devastating barrages, potentially destroying multiple high-value targets in a single turn.

B-Tier COs & Synergies

Kanbei: The Defensive Fortress

Kanbei's units are incredibly tough, boasting a 20% defense bonus, but they are also 20% more expensive. His CO Power, Morale Boost, boosts all unit attack by 10% and defense by 20%. His Super CO Power, Samurai Spirit, grants a 20% attack boost and a massive 40% defense boost.

  • Strategy: Kanbei is a slow-burn CO. His high-cost, high-defense units are excellent for holding ground and grinding down an opponent. He shines on maps where holding key positions is paramount.
  • Synergies:
    • All Units: Since all units benefit from his defense bonus, any unit becomes significantly tougher. Tanks become nearly impregnable, and even Infantry can withstand more punishment.
    • Expensive Units (Medium Tanks, Neo Tanks, Battleships): The increased defense makes the investment in these units even more valuable, as they will last much longer.
  • Actionable Steps:
    1. Early Game: Focus heavily on capturing properties to offset the increased unit cost. Be patient and build a strong defensive line.
    2. Mid Game: Use your superior defense to hold key chokepoints. When your CO Power is ready, use Morale Boost to turn your defensive line into an offensive threat.
    3. Late Game: With Samurai Spirit, your units become incredibly difficult to dislodge. Use this to push through heavily defended areas or to secure a decisive victory.

Nell: The Luck Factor

Nell's units have a small, random damage bonus (0-20%), averaging around 10%. Her CO Power, Lucky Star, increases this random bonus to 0-40%. Her Super CO Power, Lady Luck, guarantees a 50% damage bonus for all units.

  • Strategy: Nell is a high-risk, high-reward CO. While her average damage bonus is decent, her true power lies in her CO Powers, which can deliver devastating, guaranteed damage. She is best used for decisive strikes.
  • Synergies:
    • All Units: Since her bonus applies to all units, Nell can be flexible. However, units that deal high base damage (Tanks, Battleships, Bombers) benefit most from the percentage increase.
    • Units with Multiple Attacks (Fighters, Bombers): The chance for multiple high-damage rolls can be very effective.
  • Actionable Steps:
    1. Early Game: Play conservatively, building a balanced force. Don't rely on her passive luck for critical engagements.
    2. Mid Game: Save Lucky Star for a turn where you need to eliminate a high-priority enemy unit or break a defensive line.
    3. Late Game: Lady Luck is a game-changer. Use it to guarantee the destruction of multiple key enemy units, often leading to a swift end to the match. Plan your attacks carefully to maximize its impact.

C-Tier COs & Synergies

Hachi: The Bargain Hunter

Hachi's units cost 10% less, making him excellent for swarming the enemy. His CO Power, Barter, reduces unit costs by 20%. His Super CO Power, Gold Rush, reduces unit costs by 50% and allows him to build units from any owned property.

  • Strategy: Hachi's strength lies in his ability to produce a massive army. He's best on maps with many properties where he can quickly build up an economic advantage and overwhelm opponents with sheer numbers.
  • Synergies:
    • All Units: The cost reduction benefits every unit. However, cheaper units like Infantry, Recons, and Tanks become incredibly spammable.
    • Air Units (Fighters, Bombers): The cost reduction makes these expensive units more accessible, allowing for a strong air force.
  • Actionable Steps:
    1. Early Game: Focus on rapid property capture to maximize your income. Build a diverse army, taking advantage of the reduced costs.
    2. Mid Game: Use Barter to produce a surge of units, especially if you need to replace losses or make a strong push.
    3. Late Game: Gold Rush is Hachi's ultimate weapon. Use it to flood the map with units from every direction, making it nearly impossible for your opponent to defend all fronts. This is particularly effective on large maps with many properties.
