Fusiliers are a type of infantry soldier originally armed with a fusil, a lightweight flintlock musket. They were first formed in the 17th century and became known for their speed and agility on the battlefield. Over time, the term has been used to describe various regiments in different armies, particularly in Britain and France. Today, fusiliers often serve in specialized roles within modern military forces. They are typically trained for rapid deployment and may engage in both combat and ceremonial duties. Many fusilier regiments maintain a proud tradition and history, often wearing distinctive uniforms and insignia.
