 Combat Arms facts

• In general they include units that carry or employ a weapon system such as infantry, cavalry, and artillery units
• The use of multiple combat arms in mutually supporting ways is known as combined arms
• In some countries, notably the British Army, the artillery units are categorised as combat support
• Some armies such as the United States Army, classify combat engineers as a combat arm also, while armoured troops constitute a combat arm in name although many have histories derived from cavalry units
• This is also true for the combat aviation units in many armed forces throughout the world
• Artillery is included as a combat arm primarily based on the history of employing cannons in close combat, and later in the anti-tank role until the advent of anti-tank guided missiles
• The inclusion of special forces in some armed forces as a separate combat arm is often doctrinal because the troops of special forces units are essentially specialized infantry, often with historical links to ordinary light infantry units
