As acting pilot officers are junior to second lieutenants in the British Army or the Royal Marines and to Royal Navy sub-lieutenants, the rank is the most junior commissioned rank in the British Armed Forces. Senior cadets on a University Air Squadron may become acting pilot officers. The rank insignia is identical to that of a pilot officer, consisting of a thin blue band on slightly wider black band. This is worn on both the lower sleeves of the tunic or on the shoulders of the flying suit or the casual uniform."@en .
