It recruited for the Mexican War and volunteered for service but it was not needed since Pennsylvania had already supplied its required quota of troops.

The regiment served the majority of its time garrisoning and occupying the City of Baltimore as it harbored a large number of Confederate sympathizers.

It was instrumental in the apprehension of Marshal Kane, the Sheriff of Baltimore, who was a Confederate sympathizer suspected of planning revolt.

At the end of the ninety days, a large portion opted to re-enlist thus forming a new unit called the 90th Regiment Pennsylvania Volunteers.

During a skirmish at Weedon Station on July 17–18, 1864, the regiment was heavily engaged and Confederate troops had succeeded in penetrating the unit on the 90th's right flank and were in the rear of the 90th.

The regiment received the order to withdraw but lost approximately 90 men captured including its commander LTC Leech and around 20 dead and wounded.

Instead, the unit spent the majority of their service guarding several areas vital to national security to include the Dupont Powder Works in Delaware.

On October 23, 1916, while still in Texas, the regiment was converted from an infantry unit to a field artillery and trained on 4.7 inch howitzers.

After training in Georgia for several months and receiving new recruits to bring it up to combat strength, the unit was transferred to Camp Utpton in April 1918.

On May 18–19, the 108th with the rest of the 53rd FA Brigade set sail for England and arrived overseas on May 31, 1918, in Liverpool, and from there it went to Le Havre, France.

After a brief stay in Le Havre, the regiment went to train on the French artillery pieces at Fort de Meucon.

After extensive training with the French, the 108th and the rest of the 53rd FA Brigade rejoined the 28th Division on August 8, 1918, during fighting around Fismettes.

Fismettes was taken and then lost, then retaken during late August, until the Germans retreated across the Aisne River in early September.

In late 1926, after several years of discussion on its design, the regiment Coat of Arms and Distinctive Unit Insignia were approved as currently worn by members.

The 108th FA Bn fought as part of the 28th Infantry Division in Europe with M1 155mm Howitzers from Normandy Beach to the Battle of the Bulge and into Germany.

The Battalion earned five campaign streamers and was awarded the Luxembourg Croix de Guerre for actions in that country.

They were also awarded a Meritorious Unit Commendation by General Taylor, Commander of UN Forces in Korea, and two campaign streamers.

At this time the 1-108th Field Artillery was deactivated and replaced with the 108th Combat Support Hospital who carried the original 108th Campaign Honors.

In 1997 the 108th Combat Support Hospital was deactivated and the 1/108th FA was given the Lineage and Honors of the 108th Field Artillery as a challenge and trust.

Five other soldiers deployed as members of Task Force Dragoon, 2nd Brigade Combat Team, and training the Afghanistan National Army.

In September 2005, the battalion was alerted and deployed to Louisiana in support of the relief effort in the wake of Hurricane Katrina as part of the 56th SBCT.

The battalion assembled and deployed within 72 hours of alert and conducted a motor-march from their home armories to Alexandria, LA before proceeding to New Orleans.

The unit was located at Riverdale HS renamed Forward Operating Base Red Saber for the 1-108th FA and the 2-104th Cav (RSTA).

It was located here when Hurricane Rita hit and immediately after this that the Battalion re-located to Lafayette where is assisted South Central LA and established a Regional Supply Area.

Under the command of LTC Corey Lake and CSM Stephen Klunk, the battalion deployed in support of Operation Iraqi Freedom 09-11 to Camp Taji, Iraq.

They increased the indirect firing capabilities of the Battalion by establishing Firebase Arrowhead at JSS Istiqlal, Iraq.

Due to the robust and diverse civilian skillsets of the battalion members, the battalion also supported the major effort of Iraqi prisoner release as the US mission in Iraq began to wind down and further control and responsibility was transferred back to the Iraqi Government and military.

The battalion was recognized for their outstanding achievements by being awarded the Meritorious Unit Commendation at the end of their tour in Iraq.
