In French the rank is called "matelot de 2e classe". In the Royal Australian Navy, able seaman (AB) is the second-lowest of the non-commissioned member ranks, ranking above seaman and below leading seaman. Able seaman is the equivalent rank to Leading aircraftman, in the Royal Australian Air Force and Private Proficient in the Australian Army. It is not equivalent to Lance Corporal which is rated as E4, not E3 like the ranks of Able Seaman and Leading Aircraftsman. ABIS stands for Able Seaman Imagery Specialist.
