In the British Army, the captain was designated as the appropriate rank for the commanding officer of infantry companies, artillery batteries, and cavalry troops, which were considered as equivalent-level units. Captains also served as staff officers in regimental and brigade headquarters and as aides-de-camp to brigadiers and general officers. British Marine battalions also utilized captain as the appropriate rank of their constituent Marine companies. Therefore, American colonial militia and Provincial Regular units (e.g., First and Second Virginia Regiments), as well as colonial Marines, mirrored British Army and Marine organization and rank structure. </p><p>On July 23, 1775, General Washington decreed that captains would wear a "yellow or buff" cockade in their hats as their badge of rank. In 1779, the rank insignia for captains was changed to an epaulette worn of the right shoulder. Infantry captains wore a silver epaulette while all other captains wore a gold epaulette. Both company-grade officers and non-commissioned officers began wearing chevrons as rank insignia in 1821. The captain wore a single chevron, point up, above the elbow on each sleeve; again, the color was silver for infantry captains and gold for all other captains. In 1832, company-grade officers ceased wearing chevrons and reverted to a system of epaulettes (again silver for infantry and gold for all others); captains wearing an epaulette on each shoulder, but smaller and less elaborate than the field grade officer versions. In 1836, captains began wearing an insignia of two bars (gold for infantry and silver for all others). Finally, in 1872, all captains, regardless of branch, began to wear two silver bars. </p> <div class="mw-heading mw-heading2"><h2 id="Description">Description</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Captain_(United_States_O-3)&action=edit&section=2" title="Edit section: Description"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Company_commanders">Company commanders</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Captain_(United_States_O-3)&action=edit&section=3" title="Edit section: Company commanders"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>An Army captain generally serves as a battalion/squadron (cavalry) or brigade staff officer and may have an opportunity to command a <a href="/wiki/Company_(military)" class="mw-redirect" title="Company (military)">company</a>/<a href="/wiki/Artillery_battery" title="Artillery battery">battery</a> (field and air defense artillery)/<a href="/wiki/Troop" title="Troop">troop</a> (cavalry).

These captains generally serve as staff officers in battalions/squadrons (aviation), regiments/aviation groups (MAG or MACG), or in MAGTFs (MEU and MEB) and typically have an opportunity to command companies, batteries (artillery and air defense) or various types of detachments, with the title billet of company commander, for the ground units, or detachment commander, for aviation units. In the <a href="/wiki/Marine_Raider_Regiment" title="Marine Raider Regiment">Marine Raider Regiment</a>, a captain, with the title of "team leader," commands a 14-man Marine Special Operations Team (MSOT). Marine captains also serve as executive officers (i.e., second-in-command) of infantry battalion weapons companies and some other larger combat logistics and aviation support units. Marine Aviation captains routinely serve as aircraft and air mission commanders, aircraft section and division leaders, aviation maintenance department division officers, and as officers-in-charge (OIC) of various combat logistics and aviation support functional and staff sections. </p><p>An Air Force captain's authority varies by group assignment. In an operations group, senior captains may be flight commanders while more junior captains may be heads of departments. In the maintenance or logistics and mission support groups they are almost always flight commanders. In the medical group, captains usually have limited administrative and command responsibility as captain is frequently the entry-level rank for most medical officers and dental officers.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>In the Space Force, a captain typically has authority over a <a href="/wiki/Flight_(military_unit)" title="Flight (military unit)">flight</a>, and is referred to as a flight commander.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Staff_officers">Staff officers</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Captain_(United_States_O-3)&action=edit&section=4" title="Edit section: Staff officers"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Captains of all four services routinely serve as instructors at service schools and combat training centers, <a href="/wiki/Aide-de-camp" title="Aide-de-camp">aide-de-camps</a> to general officers, liaison and exchange officers to other units, services, and foreign militaries, recruiting officers, students in advanced and graduate/post-graduate programs in Professional Military Education institutions and civilian universities, and on various types of special assignments. </p> <div class="mw-heading mw-heading3"><h3 id="Specialty_branches">Specialty branches</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Captain_(United_States_O-3)&action=edit&section=5" title="Edit section: Specialty branches"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In Army and Air Force <a href="/wiki/Medical" class="mw-redirect" title="Medical">medical</a> units, captain is the entry-level rank for those possessing a medical degree, or a <a href="/wiki/Doctorate" title="Doctorate">doctorate</a> in a <a href="/wiki/Healthcare" class="mw-redirect" title="Healthcare">healthcare</a> profession.
