[citation needed] The distinctive unit insignia consists of a device of gold-colored metal and enamel, 1 inch (2.5 cm) in diameter, depicting an adaptation of the crest and motto of the coat of arms.

[citation needed] 1st Battalion, 5th Field Artillery traces its lineage to 6 January 1776, and is the oldest Regular Army unit on uninterrupted active duty.

[1] The New York Provincial Company of Artillery was led first in the American Revolutionary War by Captain Alexander Hamilton, who would later become one of the Founding Fathers of the United States.

[1] Remaining loyal to the Union in the American Civil War, "Hamilton's Own" fought valiantly in the Valley, Manassas, Antietam, Chancellorsville, Gettysburg, and Virginia 1861 Campaigns.

Captain Charles S. Chapman, Sr. commanded the force through all 5 major battles of WW I, returning to Fullerton, California to resume civilian life.

Campaign credits earned were Algeria-French Morocco, Tunisia, Sicily, Normandy, Northern France, Rhineland, Ardennes-Alsace, and Central Europe.

During Operation Fishhook in October 1968, Lieutenant Colonel Charles C. Rogers, the Battalion Commander, received the Medal of Honor for gallantry and leadership at Firebase Rita.

Today, "Hamilton's Own" serves at Fort Riley, Kansas and provides Paladin fire support to the 1st Brigade Combat Team of the 1st Infantry Division.

[citation needed] In December 2005, the battalion's AN/TPQ-36 Firefinder Radar Section was deployed in support of Operation Iraqi Freedom 4 & 5.

The team was deployed to FOB McKynzy (Samarrah East Airfields) where they supported 1-8 Infantry, 4th ID out of Fort Carson, Colorado.

[citation needed] From June through December 2011, 1st Battalion, 5th Field Artillery deployed to Kirkuk, Iraq in support of Operation New Dawn at FOB WARRIOR.

[citation needed] The mission of the 2nd Battalion, 5th Field Artillery, was to prepare for combat and, on order, deploy to a designated contingency area by air, land, and sea to provide fires in support of full spectrum operations.

It was reconstituted in the Regular Army as Battery B, 5th Field Artillery in January 1907, and organized in May 1907 from existing units at Fort Leavenworth, Kansas, and the Philippines.

During World War I the unit received credit for seven campaigns and was twice decorated with the French Croix de Guerre with two palms.

The battalion was assigned to 1st Infantry Division on 15 April 1983 at Fort Riley, Kansas (reflagging the existing 1st Battalion, 7th Field Artillery Regiment, direct support to 2nd Brigade), and then moved to Neu-Ulm, Germany as the DS FA BN for 3rd Brigade, 1st Infantry Division (aka 1st ID Forward).

This movement occurred in June 1986 (trading places with 4th Battalion, 5th Field Artillery) as part of the U.S. Army's COHORT program experiment.

Unfortunately, the same company level issues of lack of upward mobility and increased unit friction served to end the COHORT program for good.

Elements of this unit deployed to Saudi Arabia (without equipment) to support VII Corps' arrival in the Kuwait Theater of Operations (KTO).

This mission was performed by the 1st Inf Div (Mech)(Fwd) Port Support Activity (PSA), a brigade-level unit that consisted of two identical 725-man battalion task forces that included tankers, infantrymen, artillerymen, engineers, medics, mechanics and communication specialists from all units of the 1st Inf Div (Mech)(Fwd).

[citation needed] In 2000, 2-5th Field Artillery executed a battery (+) deployment to Kuwait, in direct support of Task Force Garry Owen, led by the 3rd Squadron, 7th Cavalry Regiment, an element of the 3rd Infantry Division.

[citation needed] Bravo Battery deployed in support of Operation Iraqi Freedom in February 2010, and returned to Fort Sill in 2011.

[citation needed] On 28 February 1983 the unit was redesignated as the 4th Battalion, 5th Field Artillery, assigned to the 1st Infantry Division, and activated in Neu Ulm, Germany.
