Sami is the queen of Infantry and Mech units. Her Infantry and Mechs have increased attack power and capture properties faster. Additionally, her Infantry units have a higher defense bonus. However, her direct combat vehicles (Tanks, Recons) have slightly reduced attack power. Her CO Power, 'Double Time', increases the movement of all her Infantry and Mechs by 1 and boosts their attack. Her Super CO Power, 'Victory March', allows all her Infantry and Mechs to capture properties in a single turn, regardless of their current HP.
Sami's 'build' should prioritize Infantry and Mechs. Use your fast-capturing Infantry to quickly secure an economic advantage. Mechs, with Sami's bonus, become formidable frontline units, especially in defensive terrain. While her vehicles are weaker, they are still necessary for supporting your infantry push and dealing with enemy vehicles. Sami excels on maps with many neutral cities to capture or maps with dense terrain where her Mechs can shine. Her 'Victory March' can be a game-winning power, allowing for rapid HQ captures or securing critical choke points.
