The British monarch's representatives in the counties of the United Kingdom are called Lords Lieutenant. The Lord Lieutenant of Ireland performed the function of viceroy in Ireland. In French history, "lieutenant du roi" was a title borne by the officer sent with military powers to represent the king in certain provinces. It is in the sense of a deputy that it has entered into the titles of more senior officers, lieutenant general and lieutenant colonel.
The Salvation Army also uses lieutenant to denote first time officers, or clergymen/women.
Leaders, or officers of the Boys' Brigade, particularly in the United Kingdom, are ranked as lieutenants after having completed their formal training, before which they are ranked as warrant officers. Officers serving in staff or command posts are awarded the "brevet" rank of captain, these officers then revert to their lieutenancy after having completed their tour of duty.
