By Turn 4, move your two southern Infantry to finalize the capture of the nearby neutral cities. Olaf will advance his two Tanks toward the central bridge. Position your own Tanks just outside his attack range to bait him forward. When engaging, remember that unit damage is proportional to current HP; a unit with 1 HP deals significantly less damage than one at full strength. Always prioritize attacking with your healthiest units to maximize impact.
Focus fire on a single Tank to remove it from the board, as reducing a unit's HP directly weakens its counter-attack. Use your APC to keep your frontline supplied and utilize forests for a defensive cover bonus. If your Tanks drop below 5 HP, retreat them to a captured city or your HQ; they will recover 2 HP per turn and replenish their combat effectiveness. Maintain this momentum to prevent Olaf from capturing the middle properties, ensuring your economic lead.
