A rifleman is an infantry soldier armed with a rifled long gun. Although the rifleman role had its origin with 16th century hand cannoneers and 17th century musketeers, the term originated in the 18th century with the introduction of the rifled musket. By the mid-19th century, entire regiments of riflemen were formed and became the mainstay of all standard infantry, and rifleman became a generic term for any common infantryman. History Units of musketeers were originally developed to support units of pikemen. As firearms became more effective and widely used, the composition of these pike-and-musket units changed, with pikemen eventually becoming support units to the musketeers, particularly against cavalry. The last pike regiments were dissolved by the 1720s, as pikes were superseded by the invention of the bayonet. This converted the musket into a pike for those situations where it might still be useful, such as following up volleys with a charge, crowd control, or defensive formations. Smooth-bore weapons, such as the musket, had always been recognized as relatively inaccurate, especially at longer ranges, and required massed volleys to be combat-effective. Although the smoothbore barrels impeded the accuracy of a musket, it was an advantage when loading because the looser fitting musket ball slid down the barrel quickly and easily with the ramrod being used mainly to compress the powder charge at the base of the barrel. Rifles required a tighter fit and thus more work to get the ball to be rammed all the way down the barrel. This meant that the soldiers chosen for this role needed to be good shots, resilient, brave, and resourceful. Riflemen were trained to act in isolation and were dispersed in teams of two, defending each other while they re-loaded. They were still vulnerable, especially to cavalry, as they could not present the solid wall of bayonets a larger mass of soldiers could. These factors: the time and expense required in training, the limited number of suitable recruits, and the specialized roles and situations where they were most effective meant they were highly prized, given special privileges, and used sparingly rather than squandered. Such rifle units reached their heyday in the period shortly before and during the Napoleonic Wars, with the British riflemen partially derived from units of colonial militia (see Rogers' Rangers or the Royal Americans) — truly excelling in the American War of Independence.
