Question: The 69th Pennsylvania Infantry Companies I and K wore a uniform reminiscent of regiments of which army?
Context: The 72nd Pennsylvania Infantry (originally raised as the 3rd California) was a volunteer infantry regiment which served in the Union Army during the American Civil War.  It was part of the famous Philadelphia Brigade.  They wore a very Americanized zouave uniform, consisting of a zouave jacket trimmed with red without a tombeux on the jacket, sky-blue trousers with a red stripe down the leg, a sky-blue zouave vest trimmed in red, white gaiters, and a dark blue kepi.  The jacket was decorated with 16 ball brass buttons down the front of the jacket, which were not part of the original French Zouave uniform. The 10th Pennsylvania Regiment was an American infantry unit that served in the Continental Army during the American Revolutionary War.  Raised in September 1776 in the strength of eight companies, it was assigned to George Washington's main army in December 1776.  Led by Colonel Joseph Penrose, the regiment fought under Thomas Mifflin at Princeton.  In 1777 the unit was in action at Brandywine, Paoli, and Germantown during the time Adam Hubley was lieutenant colonel.  At Monmouth in June 1778 Colonel George Nagel was in command.  A few days after Monmouth, the regiment absorbed the 11th Pennsylvania Regiment and Colonel Richard Humpton took over the unit, which grew to nine companies in size.  In 1780 the 10th fought at Springfield and Bull's Ferry.  In January 1781 the 10th Pennsylvania merged with the 1st Pennsylvania Regiment and ceased to exist. The 125th Pennsylvania Infantry volunteered during the American Civil War and served a 9-month term from August 1862 to May 1863.  It selected the motto In God We Trust.  The Regiment fought at the Battle of Antietam under the leadership of Colonel Jacob C. Higgins less than six weeks after being recruited in Blair, Cambria and Huntingdon Counties.  The Regiment was noted for its charge through the East Woods, along the Great Cornfield, down Smoketown Road, past the Dunker Church, and into the West Woods.  While in formation beyond the Dunker Church in an 'overextended' position, the Regiment repulsed four counterattacks at a price of 229 casualties (33% of engaged) within 20 minutes.  A fifth, heavily reinforced Confederate counterattack forced a retreat with a desperate struggle to retain the Regimental colors.  Two weeks before the end of their enlistment, the 125th Pennsylvania also occupied the perimeter of Chancellorsville, Virginia, during the Battle of Chancellorsville. Samuel Morton Zulick (March 1, 1824 - June 10, 1876) was an American Civil War officer and medical doctor who was promoted to brevet brigadier general of volunteers on March 13, 1865 for "bravery and efficiency as an officer".  On May 15, 1861, he enlisted as private with the 29th Pennsylvania Volunteer Infantry.  He was promoted to captain three months later.  He was later promoted to major after the Battle of Antietam and to lieutenant colonel after the Battle of Chancellorsville.  He later served at the Battle of Gettysburg and marched with Sherman to Savannah.  His father was a native of Frankfurt am Main while his mother was a native of Philadelphia.  His son, Philip S. Zulick, served in the 45th Pennsylvania Infantry. The 90th Pennsylvania Volunteer Infantry was a volunteer infantry regiment which served in the Union Army during the American Civil War.  They wore a chasseur uniform.  The uniform consisted of a dark blue habit veste with white trimming, baggy sky blue trousers, and a dark blue kepi.  The buttons on the habit veste was unique to the 90th Pennsylvania.  They were the only Union regiment in the entire war to have a specific button design. The 69th Armor is an armored (tank) regiment of the United States Army.  The 69th Armor Regiment is part of the U.S. Army Regimental System with only two battalions, the 2nd and 3rd Battalion, 69th Armor Regiment, existing in separate brigades and representing the regiment as a whole.  2–69 AR is currently stationed at Fort Benning, Georgia as part of the 3rd Armor Brigade Combat Team ("Sledgehammer"), 3rd Infantry Division and 3–69 AR is stationed at Fort Stewart, Georgia as part of the 1st Armor Brigade Combat Team ("Raider"), 3rd Infantry Division.  Both battalions have transformed from tank pure battalions into combined arms battalions (CAB), each comprising two mechanized infantry and two tank companies. The 1996 San Francisco 49ers season was the team's 51st since its inception.  In commemoration, the 49ers wore a special 50th anniversary patch.  They also wore a new uniform reminiscent of the 1994 throwback uniforms with white pants and shadowed numbers, but with a darker shade of red and an updated logo.  The franchise tied for first place in the NFC West with a 12–4 record, but lost the division title to the Carolina Panthers on the division-record tiebreaker (the Panthers had swept the Niners in the season).  The Niners were 3rd in the league in points scored and 4th in fewest points allowed. Marie Tepe (1834–1901), known as "French Mary," was a French-born vivandière who fought for the Union army during the American Civil War.  Tepe served with the 27th and 114th Pennsylvania Infantry Regiments. The Zouaves (] ) were a class of light infantry regiments of the French Army serving between 1830 and 1962 and linked to French North Africa, as well as some units of other countries modelled upon them.  The zouaves, along with the indigenous "Tirailleurs Algeriens", were among the most decorated units of the French Army. The 69th Pennsylvania Infantry (originally raised as the 2nd California) was a volunteer regiment in the Union army during the American Civil War.  Part of the famed Philadelphia Brigade, it played a key role defending against Pickett's Charge during the Battle of Gettysburg.  Companies I and K, designated as the regiment's skirmisher companies, wore a very Americanized Zouave uniform.  This uniform consisted of a dark blue Zouave jacket with green trimming, green cuffs, and sixteen brass buttons down the front on both sides of the jacket, a sky blue Zouave vest, chasseur sky-blue trousers, and a dark blue kepi.  This was one of the few Zouave uniforms that did not use red as the jacket trimming.  However, the Zouave uniforms were mostly destroyed during the Peninsula Campaign and were not replaced.
