The rank of second lieutenant (2Lt; colloquially known as a one-pip) was introduced throughout the British Army in 1877 to replace the short-lived rank of sub-lieutenant, although it had long been used in the Royal Artillery, Royal Engineers, Fusilier and Rifle regiments.
New British Army officers are normally commissioned as second lieutenants at the end of their commissioning course at RMA Sandhurst, and continue with specific training with their units, often with mentoring from senior NCOs.
