While capable of mounting offensive assaults, House Lannister's Halberdiers excel in defensive formations and positions, particularly when protecting ranged units against determined cavalry assaults. Only the most insane cavalry commander would contemplate a frontal assault against such dangerous weapons with their long reach. Even charging infantry should think twice before facing an entrenched Halberdier line. Care should be taken to shield Halberdiers from flanking maneuvers or ranged fire, but, when properly employed, nothing gets past a Halberdier's watchful eye.
