Editing First lieutenant (section)

===U.S. Revenue Cutter Service===
The term "first lieutenant" had a dual meaning in the [[United States Revenue Cutter Service]] (known until 1894 as the United States Revenue-Marine). The position title of first lieutenant was held by a junior officer who was in charge of deck operations and gunnery. The rank of first lieutenant was the equivalent of lieutenant in the current rank structure of the U.S. Coast Guard, U.S. Navy, [[United States Public Health Service Commissioned Corps]], and [[National Oceanic and Atmospheric Administration Commissioned Officer Corps]]. The next senior officer ranking above first lieutenant was captain and the next two lower officer ranks were second and [[third lieutenant]], respectively. When the Revenue Cutter Service merged with the [[United States Life-Saving Service]] to form the U.S. Coast Guard in 1915, the rank of first lieutenant carried over into Coast Guard and remained in use until 1918, when the Coast Guard adopted the rank structure of the U.S. Navy.<ref name=USCG01>Cipra, Dave; "A History of Sea Service Ranks & Titles", ''Commandant's Bulletin'', (May, June, July 1985), U.S. Coast Guard Historian's Office.</ref>
