Firearms played a significant role in the outcome of the Battle of Bunker Hill, influencing tactics and effectiveness on both sides.

American troops, armed with muskets, utilized their defensive positions to inflict heavy casualties on advancing British forces. The famous order to "not fire until you see the whites of their eyes" exemplified the importance of accuracy and discipline, maximizing the impact of their limited ammunition. Conversely, British troops faced challenges in their frontal assaults, as the close-range fire from entrenched Americans proved devastating. Overall, the effective use of firearms significantly shaped the battle's dynamics and ultimate outcomes.
