[1] The appointment was also reintroduced into the Royal Australian Army Ordnance Corps for selected warrant officers class 1 in 2005.

In February 1915, with the general introduction of warrant officers throughout the army, conductors and sub-conductors became warrant officers class I. Sub-conductors reverted to the appointment of staff sergeant major in 1967, but the appointment of conductor passed to the new Royal Logistic Corps in 1993.

It then lapsed, to be introduced back into the New Zealand Army in 1977, with he proviso that a maximum of five conductors could be appointed at any one time.

The Indian Army, however, never adopted the rank of warrant officer class I, and conductor or sub-conductor was, therefore, the only title they used.

The appointment may now be held by WO1s in any RLC trade, including transport, catering, pioneer, ammunition technician, petroleum operator and postal warrant officers, as well as the original suppliers.

A former conductor of the Royal Logistic Corps, Captain Peter Norton, won the George Cross near Baghdad on 24 July 2005.
