Light Infantry
Light Infantry battalions operate with minimal transport and sometimes almost entirely on foot. They are equipped with the full range of small arms, mortars, anti tank weaponry and surveillance equipment. The Light Role Infantry battalion is a versatile organisation that can work in support of Armoured and Mechanised manoeuvre brigades to dominate urban areas or control mountainous terrain and forests/jungle. They are employed in all major UK operations.

Mechanised Infantry
Mechanised Infantry use the Bulldog armoured personnel carrier as a form of protected mobility to move around the battlefield. Bulldog offers protection against small arms and artillery fire and provides good tactical and cross-country mobility. However, Mechanised Infantry operate on foot in the area of the Close Battle, much like Light Role Infantry.

Armoured Infantry
The Armoured Infantry are equipped with the Warrior infantry fighting vehicle. The high levels of protection, firepower, mobility and sustainability enjoyed by Armoured Infantry make them well suited to providing both shock action and the endurance element of any operational force. The Warrior is armed with a 30mm Rarden Cannon, capable of engaging vehicle and dismounted targets out to 2000m. It carries a crew of 10: driver, commander, gunner and 7 riflemen.

Air Assault Infantry
Air Assault Infantry are Light Infantry, specialised for the Air Assault role. They provide a hard hitting and versatile force that can be delivered by air, aviation or by land in support of Apache Attack Helicopter Regiments. The high speed of reaction makes such forces very useable and must be 'light, lean and lethal'. There are 4 battalions of Air Assault Infantry within 16 Air Assault Brigade, the Army's high readiness expeditionary formation.
