===Uniforms===
{{See also|Uniforms of the United States Navy}}

The uniforms of the U.S. Navy have evolved gradually since the first uniform regulations for [[officer (military)|officers]] were issued in 1802 on the formation of the Navy Department. The predominant colors of U.S. Navy uniforms are navy blue and white. U.S. Navy uniforms were based on Royal Navy uniforms of the time and have tended to follow that template.<ref>{{cite web|title=History of US Navy Uniforms, 1776–1981|url=https://www.history.navy.mil/content/history/nhhc/research/library/online-reading-room/title-list-alphabetically/h/history-of-us-navy-uniforms-1776-1981.html |website=Naval History and Heritage Command|publisher=US Navy|access-date=22 November 2016|archive-url=https://web.archive.org/web/20161209193641/https://www.history.navy.mil/browse-by-topic/heritage/uniforms-and-personal-equipment/history-of-us-navy-uniforms-1776-1981.html|archive-date=9 December 2016|url-status=live}}</ref>

==== Warrant officers ====
{{main|Warrant officer (United States)}}
{{USN Warrant Officer}}

Warrant and chief warrant officer ranks are held by technical specialists who direct specific activities essential to the proper operation of the ship, which also require commissioned officer authority.<ref name="WO-4">{{cite web|url=http://www.usawoa.org/woheritage//Hist_of_Army_WO.htm#Introduction|title=History of the Warrant Officer|publisher=United States Army Warrant Officer Association|access-date=18 March 2007|archive-url=https://web.archive.org/web/20070316213856/http://www.usawoa.org/woheritage/Hist_of_Army_WO.htm#Introduction|archive-date=16 March 2007}}</ref> Navy warrant officers serve in 30 specialties covering five categories. Warrant officers should not be confused with the [[limited duty officer]] (LDO) in the Navy. Warrant officers perform duties that are directly related to their previous enlisted service and specialized training. This allows the Navy to capitalize on the experience of warrant officers without having to frequently transition them to other duty assignments for advancement.<ref name="WO-5">{{cite web|url=http://www.usawoa.org/woheritage//WO_Prog_Other_Svc.htm|title=Warrant Officer Programs of Other Services|publisher=United States Army Warrant Officer Association|access-date=18 March 2007|archive-url=https://web.archive.org/web/20061230211659/http://www.usawoa.org/woheritage/WO_Prog_Other_Svc.htm|archive-date=30 December 2006}}</ref> Most Navy warrant officers are accessed from the [[Chief petty officer (United States)|chief petty officer]] pay grades, E-7 through E-9, analogous to a senior non-commissioned officer in the other services, and must have a minimum 14 years in service.<ref>{{cite web|url=http://www.public.navy.mil/bupers-npc/reference/messages/Documents/NAVADMINS/NAV2016/NAV16144.txt|title=Active duty limited duty officer and chief warrant officer in service procurement boards |work=[[US Navy]]|publisher=[[United States Government]]|location=Washington, D.C.|access-date=8 March 2017|archive-date=16 February 2017|archive-url=https://web.archive.org/web/20170216213241/http://www.public.navy.mil/bupers-npc/reference/messages/Documents/NAVADMINS/NAV2016/NAV16144.txt}}</ref>

E-7 to E-9 are still considered Petty Officers, but are considered a separate community within the Navy. They have separate berthing and dining facilities (where feasible), wear separate uniforms, and perform separate duties.

After attaining the rate of Master Chief Petty Officer, a service member may choose to further their career by becoming a [[Command Master Chief Petty Officer]] (CMC). A CMC is considered to be the senior-most enlisted service member within a command, and is the special assistant to the [[Commanding Officer]] in all matters pertaining to the health, welfare, job satisfaction, morale, use, advancement and training of the command's enlisted personnel.<ref name="MILCMDMC">

CMC insignia are similar to the insignia for Master Chief, except that the rating symbol is replaced by an inverted five-point star, reflecting a change in their rating from their previous rating (i.e., MMCM) to CMDCM. The stars for Command Master Chief are silver, while stars for Fleet or Force Master Chief are gold. Additionally, CMCs wear a badge, worn on their left breast pocket, denoting their title (Command/Fleet/Force).<ref name="IPUBCMC"/><ref name="BUPERSCPO">{{cite web|title=United States Navy Uniform Regulations CPO Rating |publisher=BUPERS, U.

Insignia come in the form of metal "pin-on devices" worn on formal uniforms and embroidered "tape strips" worn on work uniforms. For the purpose of this article, the general term "insignia" shall be used to describe both, as it is done in Navy Uniform Regulations. The term "badge", although used ambiguously in other military branches and in informal speak to describe any pin, patch, or tab, is exclusive to ''identification badges''<ref name="article 5201.2">
