Question: What is the name of this infantry regiment of the United States Army, whose captain was John McCunn?

 It is from New York City, part of the New York Army National Guard.  It is known as the "Fighting Sixty-Ninth", a name said to have been given by Robert E. Lee during the Civil War.  An Irish heritage unit, as the citation from poet Joyce Kilmer illustrates, this unit is also nicknamed the "Fighting Irish", immortalized in Joyce Kilmer's poem "When the 69th Comes Home". The 69th Infantry Regiment is an infantry regiment of the United States Army.  Between 1917 and 1992 it was also designated as the 165th Infantry Regiment.  It is headquartered at the 69th Regiment Armory in Manhattan. <SEP> The 65th Infantry Regiment, nicknamed "The Borinqueneers" from the original Taíno name of the island (Borinquen), is a Puerto Rican regiment of the United States Army.  The regiment's motto is "Honor et Fidelitas", Latin for "Honor and Fidelity".  The Army Appropriation Bill created by an act of Congress on 2 March 1898, authorized the creation of the first body of native troops in Puerto Rico.  On 30 June 1901, the "Porto Rico Provisional Regiment of Infantry" was organized.  On July 1, 1908, Congress incorporated the regiment into the Regular Army as the Puerto Rico Regiment of Infantry, United States Army.  On May 14, 1917, the Regiment was activated and additional men were assigned, with the unit being sent to serve at Panama.  On June 4, 1920, the Regiment was renamed 65th Infantry.  During World War II, the Regiment saw action throughout Europe, especially France and Germany, participating in Naples-Foggia, Rome-Arno and Rhin.  Several Purple Hearts were handed posthumously to members of the 65th Regiment, and the Medal of Honor was granted to Capt. Eurípides Rubio, Héctor Santiago, Carlos Lozada and Fernando García. <SEP>  He worked as a dockhand before training as a lawyer, and eventually becoming a judge.  When the American Civil War began in 1861 he joined the Union Army as a Captain in the 69th New York Infantry Regiment before he recruited the 37th New York Infantry which he commanded as colonel.  At war's end he was brevetted Brigadier General.  He was a member of the infamous Tweed Ring, which he aided by naturalising new citizens to boost his election rolls.  On one day alone, he naturalised over 2,000 new voters. John H. McCunn (Nov. 2, 1820–Jul. 6, 1872) belonged to a poor Irish immigrant family who arrived in New York City in the 19th century.  However, when the scandal was uncovered, he was impeached and removed from office. <SEP> Since the establishment of the United States Army in 1775, three regiments have held the designation 28th Infantry Regiment.  The first was a provisional unit that was constituted on 29 January 1813 and served during The War of 1812.  The second was a reorganization and redesignation of 2nd Battalion, 19th Infantry Regiment on 1 October 1866 for the American Indian Wars.  This incarnation of the 28th Infantry Regiment lasted until 15 March 1869, when it was consolidated back into the 19th Infantry Regiment.  The third version of the 28th Infantry Regiment is the one that has the permanent designation and history, and is the one this article is about.
