Editing Sub-lieutenant (section)

=== Use ===
In the Royal Navy, the [[Royal Australian Navy]] and the [[Royal New Zealand Navy]], the insignia of both sub-lieutenants and acting sub-lieutenants consists of one medium [[gold braid]] stripe with an [[executive curl]]. The size of this stripe should not be confused with the narrow stripe, colloquially referred to as "spaghetti strap", used on the [[Royal New Zealand Navy]] rank of [[Ensign (rank)|ensign]] and the [[Royal Canadian Navy]]'s [[Officer Cadet|naval cadets]]. The Royal Air Force also followed this example of braiding when developing their rank system (see [[flying officer]]).

The insignia of sub-lieutenants in most commonwealth countries are identical to the [[United States Navy]] and [[United States Coast Guard]] grade of ensign (although US ranks do not use the executive curl), even though its equivalent grade in the USN is actually [[lieutenant junior grade]].

In the [[Royal Canadian Navy]], acting sub-lieutenants display one medium stripe. A sub-lieutenant adds a narrow stripe ''below'' the medium stripe to maintain the executive curl on the top. The equivalent air force lieutenant rank has the narrow stripe above the medium stripe since these elements do not need to maintain spacing on top due to the lack of an executive curl; the Royal Canadian Navy followed this pattern before the addition of the curl in 2010.
