Irregular warfare in the context of "Raid (military)"

The Troubles (Irish: Na Trioblóidí) were an ethno-nationalist conflict in Northern Ireland that lasted for about 30 years from the late 1960s to 1998. Also known internationally as the Northern Ireland conflict, it began in the late 1960s and is usually deemed to have ended with the Good Friday Agreement of 1998. Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England, and mainland Europe.

Sometimes described as an asymmetric or irregular war or a low-intensity conflict, the Troubles were a political and nationalistic struggle fueled by historical events, with a strong ethnic and sectarian dimension, fought over the status of Northern Ireland. Unionists and loyalists, who for historical reasons were mostly Ulster Protestants, wanted Northern Ireland to remain within the United Kingdom. Irish nationalists and republicans, who were mostly Irish Catholics, wanted Northern Ireland to leave the United Kingdom and join a united Ireland. Despite the division between Protestants and Catholics, it was not primarily a religious war.

Irregular military is any military component distinct from a country's regular armed forces, representing non-standard militant elements outside of conventional governmental backing. Irregular elements can consist of militias, private armies, mercenaries, or other non-state actors, though no single definition exists beyond exclusion from national service. Without standard military unit organization, various more general names are often used; such organizations may be called a troop, group, unit, column, band, or force. Irregulars are soldiers or warriors that are members of these organizations, or are members of special military units that employ irregular military tactics. This also applies to irregular infantry and irregular cavalry units.

Irregular warfare is warfare employing the tactics commonly used by irregular military organizations. This often overlaps with asymmetrical warfare, avoiding large-scale combat and focusing on small, stealthy, hit-and-run engagements.

The Spanish American wars of independence (Spanish: Guerras de independencia hispanoamericanas) took place across the Spanish Empire during the early 19th century. The struggles in both hemispheres began shortly after the outbreak of the Peninsular War, forming part of the broader context of the Napoleonic Wars. The conflict unfolded between the royalists, those who favoured a unitary monarchy, and the patriots, those who promoted either autonomous constitutional monarchies or republics, separated from Spain and from each other. These struggles ultimately led to the independence and secession of continental Spanish America from metropolitan rule, which, beyond this conflict, resulted in a process of Balkanization in Hispanic America. If defined strictly in terms of military campaigns, the time period in question ranged from the Battle of Chacaltaya (1809) in present-day Bolivia, to the Battle of Tampico (1829) in Mexico.

These conflicts were fought both as irregular warfare and conventional warfare. Some historians claim that the wars began as localized civil wars, that later spread and expanded as secessionist wars to promote general independence from Spanish rule. This independence led to the development of new national boundaries based on the colonial provinces, which would form the future independent countries that constituted contemporary Hispanic America during the early 19th century. Cuba and Puerto Rico remained under Spanish rule until the 1898 Spanish–American War.

A militia (/mɪˈlɪʃə/ mil-ISH-ə) is a military or paramilitary force that comprises civilian members, as opposed to a professional standing army of regular, full-time military personnel. Militias may be raised in times of need to support regular troops or serve as a pool of available manpower for regular forces to draw from.

When acting independently, militias are generally unable to hold ground against regular forces. Militias commonly support regular troops by skirmishing, holding fortifications, or conducting irregular warfare, instead of undertaking offensive campaigns by themselves. However, militias may also engage in defense activities to protect a community, its territory, property, and laws. For example, naval militias may comprise fishermen and other civilians which are organized and sanctioned by a state to enforce its maritime boundaries.

Brigadier General Francis Marion (c. 1732 – February 27, 1795), also known as the "Swamp Fox", was an American military officer, planter, and politician who served during the French and Indian War and the Revolutionary War. During the American Revolution, Marion supported the Patriot cause and enlisted in the Continental Army, fighting against British forces in the southern theater of the American Revolutionary War from 1780 to 1781.

Though he never commanded a field army or served as a commander in a major engagement, Marion's use of irregular warfare against the British has led him to be considered one of the fathers of guerrilla and maneuver warfare, and his tactics form a part of the modern-day military doctrine of the U.S. Army's 75th Ranger Regiment.

Skirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They may be deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale. Such tactics are collectively called skirmishing. An engagement with only light, relatively indecisive combat is sometimes called a skirmish even if heavier troops are sometimes involved.

Skirmishers can be either regular army units that are temporarily detached to perform skirmishing or specialty units that were specifically armed and trained for such low-level irregular warfare tactics. Light infantry, light cavalry (historically), and irregular units often specialize in skirmishing. Skirmishers' open formations and smaller numbers can give them superior mobility over the regular forces, allowing them to engage only on favorable terms, taking advantage of better position or terrain, and quickly withdrawing from any threat of superior enemy forces. Though often critical in protecting the main army from sudden enemy advances, skirmishers were historically poor at taking or defending ground from heavy infantry or heavy cavalry.
