Max is a powerhouse when it comes to direct combat units. His Tanks, Medium Tanks, Recons, and other direct attack units receive a significant attack bonus. However, this comes at a cost: his indirect combat units (Artillery, Rockets, Missiles) have reduced attack range and power. His CO Power, 'Max Force', further boosts his direct combat units' attack by 20% for one turn, and his Super CO Power, 'Max Blast', provides an even greater boost and extends movement range.
When playing as Max, your 'build' should heavily favor direct combat units. Focus on producing Tanks, Medium Tanks, and Anti-Air units. Infantry are still essential for capturing, but don't rely on indirect fire for your main offensive. Your strategy should involve aggressive pushes, using your superior direct combat power to overwhelm the enemy. Be mindful of his indirect unit weakness; if the enemy has strong Artillery, you'll need to close the distance quickly or use air units to eliminate them. Max excels on maps with open terrain where his direct units can maneuver and engage effectively.
