The 66th Armor Regiment is the oldest Armored unit in the United States Army, tracing its lineage to the beginning of the Tank Service in February 1918 under the command of Col. George S. Patton.
What would become the 66th Armored Regiment was originally organized as the 1st and 2d Provisional Brigades, United States Tank Corps. The regiment participated in the battle of St. Mihiel, France, where it received its baptism of fire while attached to the 1st Infantry Division in the Meuse-Argonne, and the Somme Offensives.
The casualties among the officers and men were heavy during the short period the regiment participated in World War I and their valor was recognized by General John J. Pershing in the following words: "The percentage of casualties among the officers and men tells the tale of splendid morale and gallantry in action and their unselfish devotion to duty".
Between the world wars the numerical designation of the regiment was changed several times. On 15 July 1940, the unit was redesignated from the "66th Infantry (Light Tanks)" to "66th Armored Regiment" as part of the newly-formed 2nd Armored Division, stationed at Fort Benning, Georgia.
World War II
In December 1942, the regiment participated in the amphibious invasion of French Morocco in North Africa and led the division's entry into Casablanca. The regiment participated in the invasion of Sicily and through fierce fighting earned the unit six battle streamers during the war.
During WWII tank crews of the 66th Armored Regiment were primarily equipped with the M4 Sherman medium tank and the M5 Stuart light tank.
As a result of its exemplary conduct in the liberation of Belgium, the regiment was twice cited in the Order of the Day of the Belgian Army. Captain James M. Burt, the commander of B Company, 66th Armored Regiment, was awarded the Medal of Honor for his heroism during the Battle of Aachen in October 1944. Captain Burt later served as Honorary Colonel of the Regiment.
Cold War
Following the war, elements of the 66th and other units of the 2nd Armored Division were selected to occupy the American sector of Berlin and serve as the first American troops to enter the fallen German capital.
During the Korean War, an offspring of the 66th fought under the designation "6th Tank Battalion". During the war, the sixth won seven battle streamers and the Korean Presidential Unit Citation. These honors were awarded to the 66th Armored Regiment when the 6th Tank Battalion was deactivated after the conflict.
Throughout the Cold War the four battalions of the regiment served in the 2nd Armored Division at Ft. Hood, Texas, and as part of the 2nd Armored Division (Forward) in the Federal Republic of Germany.
Desert Storm
In 1991, during Operation Desert Storm, the regiment again proved its worth by assisting in the liberation of Kuwait and the defeat of the Iraqi army. The 2nd and 3rd battalions of the regiment, stationed in Germany as part of the 2nd Armored Division (Forward), deployed and fought under the operational control of the 1st Infantry Division. The 4th battalion, along with the 3d (Phantom) Brigade of the 3rd Infantry Division, was attached to the 1st Armored Division. The Phantom Brigade became the 1st Armor's lead brigade for VII Corps' "left hook" to smash the Iraqi Republican Guard divisions.
Soldiers from 1st Battalion, 66th Armored Regiment conduct a cordon and search operation in Sheik Hamid, Iraq.
In the Spring of 1995, the 1st Battalion of the 66th was assigned to assist over 5,000 Cuban and Haitian refugees interned at Guantanamo Bay, Cuba.
66th Armor Today
As of 2008 two battalions of the regiment are still in active service. First Battalion is assigned to the 1st Brigade of the 4th Infantry Division at Ft. Carson. The First Battalion has participated in combat operations in Operation Iraqi Freedom. On March 17, 2008 1st Battalion, 77th Armor was reflagged as 3rd Battalion, 66th Armor as part of the activation ceremony of the 172nd Infantry Brigade (United States). The unit is currently stationed at Grafenwoehr, Germany.

Symbolism
The coat of arms was originally approved for the 15th Tank Battalion, part of which was in the old 304th Tank Brigade. Therefore, the shield and crest of the 304th Tank Brigade are used with the label added for difference.
The Brigade was organized at Langres, France, in 1918, and the arms of Langres are shown on an inescutcheon differenced by a silver border and changing the cross from red to silver.
The wyvern is from the original insignia of the French Tank Corps.
The uprooted pine tree commemorates the activities of the brigade in the Argonne Forest during the Meuse-Argonne operations.
