In 1899, General Loyd Wheaton, with a force under his command which included elements of the regiment, perpetrated a massacre of Filipino civilians in the town of Titatia.

A. Barnes, a soldier in the G Battery of the regiment, wrote a letter to his brother describing the massacre: The town of Titatia was surrendered to us a few days ago, and two companies occupy the same.

Immediately orders were received from General Wheaton to burn the town and kill every native in sight; which was done to a finish.

The 9th Armored Division landed in Normandy late in September 1944, and first went into the line, 23 October 1944, on patrol duty in a quiet sector along the Luxembourg-German frontier.

When the Germans launched their winter offensive on 16 December 1944, the 9th, with no real combat experience, suddenly found itself engaged in heavy fighting.

The division saw its severest action at St. Vith, Echternach, and Bastogne, its units fighting in widely separated areas.

Its stand at Bastogne held off the Germans long enough to enable the 101st Airborne Division to dig in for a defense of the city.

The division exploited the bridgehead, moving south and east across the Lahn River toward Limburg, where thousands of Allied prisoners were liberated from Stalag XIIA.

In February 2023, the 5th Battalion, 3rd Field Artillery Regiment (5-3 LRFB) — 1st MDTF's long-range fires battalion— deployed the Long-Range Hypersonic Weapon (LRHW), a medium-range surface-to-surface hypersonic missile, from Joint Base Lewis-McChord, Tacoma, Washington to Cape Canaveral, Florida, a distance of 3,100 miles.

[4][5] The 1st Battalion, 3rd Field Artillery Regiment served with the 2nd Armored Division in Germany and at Fort Hood, Texas, from 1957 - 1991, including service in Operations Desert Shield and Storm.

Prior to the commencement of the main ground offensive, Bravo Battery provided fire support in the form of Artillery Raids to the 2nd Marine Light Armored Infantry whose mission was to scout out possible alternate breach points, identify and locate Iraqi Artillery for counter battery attack, and to draw attention away from the main forces approach points.

The 2nd Battalion, 3rd Field Artillery Regiment served with the 3rd Armored Division from 1957 to 1991, including service in Operations Desert Shield and Storm.

[12] 4th Battalion of the 3rd Field Artillery Regiment was part of the 2nd Armored Division (Forward), stationed in Garlstedt, Germany.

During the 1st Gulf War 4-3 FA Battalion was chosen to be the main fire support element of Task Force 1-41 Infantry.

On 15 February 1991 4-3 FA Battalion fired on a trailer and a few trucks in the Iraqi sector that was observing American forces.

[15] On 16 February 1991 several groups of Iraqi vehicles appeared to be performing reconnaissance on Task Force 1-41 and were driven away by fire from 4-3 FA Battalion.

[19] 4-3 FA Battalion conducted a significant number of fire missions and artillery raids at the breach of initial Iraqi defenses.

[21] These missions destroyed the vast majority of Iraq's artillery assets and inflicted heavy casualties on Iraqi infantry units.

[25] Prior to the major ground assault, 4-3 FA Battalion participated in a 90,000 round artillery preparation against Iraqi defensive targets.

[28] During the early stages of the battle 4-3 FA participated in fire missions against Iraqi targets a dozen miles to the east.

[29] At the Battle of Norfolk 4-3 FA had a hand in the destruction of 60 Iraqi tanks and 35 Infantry fighting vehicles just west of the IPSA pipeline.

[31][37] The Battery C Advance Party/Reconnaissance Team and other elements of Task Force 1-41 Infantry managed to hold their position against an Iraqi Republican Guard unit until Task Force 3-66 Armor arrived on the scene which resulted in the defeat of the Republican Guard unit and several Iraqi soldiers becoming prisoners of war.

[40] 4-3 FA battalion and the rest of 1st Infantry Division artillery destroyed 50 tanks, 139 APCs, 30 air defense systems, 152 artillery pieces, 27 missile launchers, 108 mortars, and 548 wheeled vehicles, 61 trench lines and bunker positions, 92 dug in and open infantry targets, and 34 logistical sites.

The battalion deployed multiple times to Operation Iraqi Freedom, and moved with the 17th Field Artillery Brigade to Joint Base Lewis-McChord, Washington, where it is currently stationed.

The rising sun indicates the regiment dates back nearly to the dawn of this country's history (Battery "D" was organized in 1802), and the Aztec banner is for the Mexican War.
