British soldiers were generally regarded as more disciplined compared to the colonial militia during the battles of Lexington and Concord.

The British forces were composed of professional soldiers, expertly trained in formal military drills and tactics, and were used to following strict orders and maintaining organized formations. In contrast, the colonial militia was made up of local volunteers with varying levels of training and experience, often employing guerrilla tactics instead of conventional military discipline. Although the militia demonstrated impressive courage and resilience, the training of the British soldiers provided them with an advantage in organization and control during combat, underscoring the disparities in military readiness between the two groups.
