17th Cavalry Regiment ( United States ) The 17th Cavalry is a historical organization within the United States Army that began as a regiment of cavalry after the Pancho Villa Expedition . The unit was constituted on 1 July 1916 in the Regular Army as the 17th Cavalry at Fort Bliss , Texas and originally inactivated 26 September 1921 at the Presidio of Monterey , California . Formerly a part of the 1950s Combat Arms Regimental System , it was reorganized as a part of the United States Army Regimental System , an ongoing effort to maintain the lineage and history of the Army through its units . Today , the 17th Cavalry Regiment is found across the Army within the Combat Aviation Brigade s , where the Squadrons , now constituted as attack / recon helicopter squadrons , carry on the legacy of the 17th Cavalry Regiment . History . Formation . The 17th Cavalry Regiment was organized under the provisions of the National Defense Act of 1916 at Ft Bliss , Texas on 30 June 1916 and constituted on 1 July 1916 . General Pershing had taken his columns into Mexico only a short time before and the need of cavalry troops was pressing . Thirty - two officers and seven hundred ninety - one veterans from the 1st , 3rd , 6th , 8th and 14th Regiments were transferred as the nucleus of the new regiment . Many of these were recalled from the Punitive Expedition and since all were experienced troopers , little time was spent in whipping the organization into shape . The Regimental Commander , Colonel Willard A . Holbrook , assumed command on 9 July 1916 , on which date the men from the 8th Cavalry joined the regiment . Colonel Holbrook held command until he was promoted to the rank of Major General . In honor of the cavalry regiments that contributed officers , men and experience to the formation of the 17th Cavalry Regiment , the regimental shield shares much from the coats of arm of those units . Orange is from the lst Cavalry and was the official color that has historically represented dragoons . The color green was taken from the 3d Cavalry . Their uniforms contained green facings in honor of the 3d Cavalry ' s first engagement at Vera Cruz , and its contribution throughout the campaign of 1847 to the capture of Mexico City . The Regiment chose the unicorn from the 6th Cavalry Regiment , which represents the knightly virtues and , in the rampant position , a symbol of fighting aggressiveness , combined with speed and alacrity . The demihorse , in honor of cavalry mounts , was taken from the shield of the 8th Cavalry Regiment . The diagonal line , being the traditional military symbol of cavalry , came from the 14th Cavalry . The first mounted formation of the regiment was held on 4 August 1916 and consisted of all fifteen troops and the wagons of the supply Troop . Arizona . 14 May 1917 , the Regiment received orders for a change of station due to disturbances along the border of Arizona . By 17 May , the Regiment loaded up on trains and traveled from El Paso to arrive at Douglas , Arizona , on the mid - afternoon of 18 May . The Regiment established itself at " Camp Harry J . Jones " , Douglas , Arizona , with outposts near Naco , Arizona ( 30 miles west along the border ) , west of town near the C & A Copper Smelter , Forrest , Arizona , and Slaughter ' s Ranch ( 13 miles east ) . Trouble began in the copper mining districts of Arizona as the Union ( IWW ) became unmanageable . On 5 July 1917 a provisional squadron , under the command of Lieutenant Colonel White , marched north to Globe , Arizona , for strike duty . Later that month , forest fires in Mormon Canyon ( Turkey Creek ) grew beyond the control of the forest rangers , prompting another call for assistance by the civil leaders ; a detail of fifty men under 2nd Lieutenant Arthur S . Harrington was deployed to assist them . The Regiment would remain in the Southwest until the end of the war . After the armistice was signed , the Regiment was under orders to move to Hawaii . Hawaii . On 5 April 1919 , the 17th Cavalry set sail from San Francisco on the USAT . Sherman , bound for Honolulu and Schofield Barracks . The massive demobilization following the end of World War I , would leave the 17th Cavalry manning the garrison at Fort Shafter and Schofield Barracks until the fall of 1920 . Still , the problem remained of covering approximately one hundred miles of rugged coast line with one regiment of cavalry to effectively repel any attempted landing of troops from transports and hold them off until the arrival of reinforcements . With the exception of the sector in and around the city of Honolulu and Pearl Harbor , the entire coast line of the island was left to the 17th Cavalry Regiment . The Regiment developed an intricate system of shielded lights and telephone lines for command and control as well as reporting , with camps placed in locations that provided excellent cover and concealment from the air or sea . Reorganization in 1921 resulted in a reduction of the number of cavalry regiments from seventeen to fourteen , this included inactivation of the 17th Cavalry . Lack of funds , reduced personnel authorization , and serious doubts that " the mounted combat of large bodies of cavalry is probably a thing of the past " contributed to the decision as well as a new regimental organization that was designed to reduce overhead , increase firepower , and retain mobility . Many old , famous cavalry units came dangerously close to being lost to the Army because of organizational changes , but a new policy of retaining surplus units on the rolls of the Army in an inactive status was established , preserving unit designations and histories for future use rather than disbanding or re - designating them . The regiment left Schofield Barracks by truck for Honolulu on 16 September and embarked on the USAT . Buford for Monterey , California . The officers and enlisted men were transferred to the 11th Cavalry on 26 September , and the 17th Cavalry was placed on the inactive list . Vietnam .

The 2d Squadron , 17th Cavalry was originally deployed to Vietnam on 12 December 1967 as the ground cavalry squadron of the 101st Airborne Division , but as the division changed to an airmobile mode the squadron was converted to an air cavalry status during the period December 1968 - June 1969 . Troops A , B and C ( airmobile aviation ) thus joined the squadron in March 1969 to complete the conversion . It should be noted that the previous Troop A ( ground reconnaissance ) had been serving the 1st Brigade of the division since 29 July 1965 . The entire squadron was involved in intense aerial combat during the Operation LAM SON 719 invasion of Laos , when the helicopters supported the South Vietnamese Army ' s drive and retreat directly .

Troop A deployed under the command of Captain Bill Carpenter ( Lonesome End West Point football ) , who called in napalm air strikes on his own position as it was being overrun . Departing from this battle , Troop A patrols were tasked to rescue and reinforce Lieutenant Colonel David Hackworth ' s Tiger Force ( the battalion recon platoon of the 1st Battalion , 327th Infantry ) of 45 soldiers who had been overrun and outnumbered 40 or more to 1 . The 80 men of Troop A were at that time deployed in reconnaissance efforts along the Ho Chi Minh Trail and throughout the Dak To Province . Each of the 12 patrols rendezvoused with a chopper flight to fight their way in to rescue and re - enforce Tiger Force . The scout ' s radio frequency was changed to Tiger Force as it did every time the scouts were officially attached to another unit .
