# 78th Infantry Division (United States)

The 78th Training Division (Operations) ("Lightning") is a unit of the United States Army which served in World War I and World War II as the 78th Infantry Division, and currently trains and evaluates units of the United States Army Reserve for deployment.

## World War I

The 78th Division of the United States Army was constituted on 5 August 1917 and activated on 23 August 1917, over four months after the American entry into World War I, at Camp Dix, New Jersey. It consisted of four infantry regiments: the 309th, 310th, 311th and 312th; and three artillery Regiments: the 307th, 308th and 309th.
The division was originally allocated to New York and northern Pennsylvania in the National Army recruiting plan. While the headquarters of the 78th Division was activated in August, with the first draftees arriving in September, it was not fully active until early 1918. After several more months of training, the 78th was transported to France in May and June 1918.
In France, during the summer and fall of 1918, it was the "point of the wedge" of the final offensive which knocked out Germany. The 78th was in three major campaigns during World War I – Meuse-Argonne, St. Mihiel, and Lorraine. The division was demobilized on 9 July 1919 at Camp Dix, New Jersey.

## Interwar period

The division was reconstituted in the Organized Reserve on 24 June 1921, allotted to the Second Corps Area, and assigned to the XII Corps with the state of New Jersey as its home area. The division headquarters was organized on 1 July 1921 at 39 Whitehall Street in Manhattan, but relocated on 26 March 1924 to the Globe Indemnity Building, Washington Place, Newark, New Jersey. The headquarters was relocated on 25 July 1936 to the Federal Building, 1180 Raymond Boulevard in Newark and remained there until activated for World War II. Like the 77th Division, the initial formation of the “Lightning Division” was expedited by the enrollment of many officers who were World War I veterans of the division. To maintain communications with the officers of the division, the division staff published a newsletter, the “78th Division Gazette.” The newsletter informed the division’s members of such things as when and where the inactive training sessions were to be held, what the division’s summer training quotas were, where the camps were to be held, and which units would be assigned to help conduct the Citizens Military Training Camps (CMTC). The designated mobilization and training station for the division was Camp Dix, the location where much of the 78th’s training activities occurred in the interwar years. The division headquarters often conducted its summer training there, and on a number of occasions, participated in CPXs at Camp Dix as well. The 78th Division headquarters also occasionally trained with the staffs of the 1st Division or the 1st Infantry Brigade at Camp Dix. In 1924, the division officers with assistance from Colonel Edward A. Shuttleworth, the division chief of staff, established Camp Silzer at Sea Girt, New Jersey, for the purposes of providing a training area for the division. Camp Silzer was used some summers by the division staff for command post exercises and frequently for “contact camps” by subordinate units. For the 1937 camp at Camp Dix, the division staff and subordinate units planned and conducted an unusual division night attack exercise in coordination with the 303rd Chemical Regiment and the 40th Engineer Battalion (Camouflage). As of 1937, the division was commanded by Brigadier General Perry L. Miles.
The subordinate infantry regiments of the division held their summer training primarily with the units of the 1st Infantry Brigade. Other units, such as the special troops, artillery, engineers, aviation, medical, and quartermaster, usually trained at various posts in the Second and Third Corps Areas also with other units of the 1st Division. For example, the division’s artillery units trained with the 7th Field Artillery at Pine Camp, New York; the 303rd Engineer Regiment usually trained with the 1st Engineer Regiment at Fort DuPont, Delaware; the 303rd Medical Regiment trained with the 1st Medical Regiment at Carlisle Barracks, Pennsylvania; and the 303rd Observation Squadron trained with the 5th Observation Squadron at Mitchel Field, New York. In addition to the unit training camps, the infantry regiments of the division rotated responsibility for conducting the infantry CMTC held at Camp Dix each year. On a number of occasions, the division participated in Second Corps Area or First Army command post exercises in conjunction with other Regular Army, National Guard, and Organized Reserve units. These training events gave division staff officers’ opportunities to practice the roles they would be expected to perform in the event the division was mobilized. Unlike the Regular Army and National Guard units in the First Corps Area, the 78th Division did not participate in the Second Corps Area maneuvers and the First Army maneuvers of 1935, 1939, and 1940 as an organized unit due to lack of enlisted personnel and equipment. Instead, the officers and a few enlisted reservists were assigned to Regular Army and National Guard units to fill vacant slots and bring the units up to war strength for the exercises. Additionally, some were assigned duties as umpires or as support personnel.

## World War II

Before Organized Reserve infantry divisions were ordered into active military service, they were reorganized on paper as "triangular" divisions under the 1940 tables of organization. The headquarters companies of the two infantry brigades were consolidated into the division's cavalry reconnaissance troop, and one infantry regiment was removed by inactivation. The field artillery brigade headquarters and headquarters battery became the headquarters and headquarters battery of the division artillery. Its three field artillery regiments were reorganized into four battalions; one battalion was taken from each of the two 75 mm gun regiments to form two 105 mm howitzer battalions, the brigade's ammunition train was reorganized as the third 105 mm howitzer battalion, and the 155 mm howitzer battalion was formed from the 155 mm howitzer regiment. The engineer, medical, and quartermaster regiments were reorganized into battalions. In 1942, divisional quartermaster battalions were split into ordnance light maintenance companies and quartermaster companies, and the division's headquarters and military police company, which had previously been a combined unit, was split.
The 78th Infantry Division was reorganized effective 20 February 1942, and was ordered into active military service on 15 August 1942 and reorganized at Camp Butner, North Carolina, and concurrently redesignated as Headquarters, 78th Infantry Division. It was designated as a replacement pool division on 1 October 1942, and remained in this assignment until 1 March 1943, when the 78th Division was restored to field duty, and to its training regimen. 78th Division moved to the Carolina Maneuver Area on 15 November 1943 to test its training, and then returned to Camp Butner on 7 December 1943. The personnel then went on Christmas leave, and deployed to the Tennessee Maneuver Area on 25 January 1944, where they participated in the 5th Second Army Tennessee Maneuvers. They then moved to Camp Pickett, Virginia, where they filled their TO&E, (table of organization and equipment), then deployed to the staging area at Camp Kilmer, New Jersey, on 4 October 1944.
After two years as a training division, the 78th embarked for the European Theatre from the New York POE on 14 October 1944, whereupon they sailed for England. They arrived on 26 October 1944, and after further training crossed to France on 22 November 1944.
After landing in France, the division moved to Tongeren, Belgium, on 27 November 1944, and to Roetgen, Germany, on 7 December 1944, to prepare for combat. The 311th Infantry Regiment was attached to the US 8th Infantry Division in the Hurtgen Forest, 10 December. The 309th and 310th Infantry Regiments relieved elements of the 1st Division in the line in the vicinity of Entenpfuhl, 1–12 December. On the 13th these regiments smashed into Simmerath, Witzerath, and Bickerath and were fighting for Kesternich when Gerd von Rundstedt launched his counteroffensive in the Monschau area, on 18 December.
The 78th held the area it had taken from the Siegfried Line against German attacks throughout the winter. The Division attacked, 30 January 1945, and took Kesternich, 2 February, the town of Schmidt on the 8th, and captured intact the vital Schwammanauel Dam the next day. In the advance, the Roer River was crossed, 28 February, and the division joined the offensive of the First and Ninth Armies toward the Rhine. That river was crossed over the Ludendorff Bridge at Remagen, 8 March, by the 310th Regiment, the first troops to cross in the wake of the 9th Armored Division. That unit, attached to the 9th Armored and acting as a motorized unit had driven across Germany capturing Euskirchen, Rheinbach, and Bad Neuenahr. The 78th expanded the bridgehead, taking Honnef and cutting part of the Autobahn, 16 March. From 2 April to 8 May, the division was active in the reduction of the Ruhr Pocket and at VE-day was stationed near Marburg. In mid-November 1945 the division relieved the 82nd Airborne Division on occupation duty in Berlin.$^{:130}$ In May 1946, the 3rd Inf Regiment was moved to Berlin and on 15 June, it took over the Berlin Military District from the division.
The 78th Infantry Division was subsequently inactivated at Berlin on 16 June 1946. The division's infantry regiments were also inactivated as follows: 309th Infantry Regiment between 15 Apr – May 22, 1946, in Germany; 310th Infantry Regiment on 15 Jun 1946, at Berlin; 311th Infantry Regiment on 22 May 1946, in Germany. The division remained on occupation duty in Germany until it was inactivated on 22 May 1946.

## Post-war service

On 1 November 1946, the 78th Infantry Division was reactivated at Newark, New Jersey. The headquarters location was changed on 9 November 1955 to Kearny, New Jersey, and on 6 December 1958 to Edison, New Jersey.
The 78th Division was deployed to Southwest Asia 1990 and 1991 when the 920th Transportation Company (Medium, Petroleum) to support operations in Desert Storm. The 1018th Reception Battalion, the 2nd Brigade OSUT Headquarters, and the 1st and 3rd Battalion of the 310th Regiment as well as the 1st Brigade's 3rd Battalion, 309th Regiment with a composite detachment from the 78th Training Support Brigade, provided assistance in necessary training base expansion at Fort Dix. The 348th Military Police Detachment conducted protective service missions for key national leaders throughout the world during the mobilization period. In addition, many individuals from the 78th served as "fillers" in other deployed units.
On 1 October 1993, the division was reorganized and redesignated as Headquarters, 78th Division (Exercise), under the Army's "Bold Shift" initiative. The new mission is to conduct small unit collective training (LANES) and computerized battle simulation exercises for client units in the First Army East area (a 14 state region). Like the other exercise divisions, the 1st Brigade was designated as the simulations exercise unit, conducting Battle Command and Staff Training for US Army Reserve and Army National Guard units at the battalion, brigade, command, and division levels. This training uses the simulations models used by the Regular Army in conducting WARFIGHTER exercises. The other brigades within the division (2d through 5th depending on the division) conducted field training for units at the squad, platoon, and company levels. In all units, then made up of US Army Reserve soldiers, there were detachments of Regular Army soldiers assigned to manage the day-to-day requirements and planning of exercises as part of the Congressionally mandated Ground Forces Readiness Enhancement (GFRE – popularly known as "Jeffries") program. This program was partially instituted to ensure that reserve component units would have continual training support in order to preclude some of the training and readiness problems that were discovered in the ramp-up, and eventual deployments, in support of Desert Storm.
One of five exercise divisions in the United States Army, the 78th Division Headquarters, and its 1st Brigade, were for many years headquartered at the Kilmer Reserve Center (the former Camp Kilmer) in Edison, New Jersey, with subordinate units located in New Jersey, Rhode Island, Massachusetts, Virginia, Maryland, Pennsylvania and New York.
As a result of the 2005 BRAC, the division's headquarters and its 1st Brigade were relocated to Fort Dix, New Jersey, joining the already located Division's 2d Brigade (LANES) and some 1st Brigade (BCST) subordinate elements.
On 17 October 1999, the division was redesignated from 78th Division (Exercise) to 78th Division (Training Support) to reflect the growing change in the type of training provided by the division's units. There was also an associated change in the manning of the unit, adding National Guard personnel to the regulars and Army Reservists already assigned. This was one of the first instances of the growing multi-component organization of US Army units that deal with Reserve Component training and operations.
In 1999, the 189th Infantry Brigade was reflagged as the 4th Brigade, 78th Division (TS) and merged with the existing 4th Brigade, 78th Division (Exercise). The reorganization created a unique unit consisting of active-component, National Guard, civilian and drilling US Army reservists. On 1 October 2009, the division was reorganized and redesignated as Headquarters, 78th Training Brigade, and on 1 October 2010, it was reorganized and redesignated as Headquarters, 78th Training Division.
The 4th Brigade is a tenant unit on Fort Bragg with headquarters at the 78th Division (Training Support), Edison, New Jersey. The brigade's responsibility is to train, coach, teach and mentor the Reserve and Army National Guard units of North Carolina.
The 4th Brigade, 78th Division (Training Support) provides training assistance, support, and evaluation to priority Reserve Component units and all other units within capabilities. Synchronize training support within area of responsibility in order to enhance individual and unit readiness to meet directed mobilization and/or wartime requirements. On order, activate or augment mobilization assistance teams (MAT) to assist installation commanders in post-mobilization training and validation of mobilized units for deployment. On order, deploy a defense coordinating officer (DCO) and/or a defense coordinating element (DCE) to coordinate military support to civilian authorities (MSCA) during federal disaster response operations. Provide command and control of subordinate units.
1st BN (LS), 313th Regiment, 4th BDE, provides logistic support for a multi-component (AC/USAR/ARNG) training support brigade that conducts lanes training, TAM evals for priority RC client units; On order provides mobilization augmentation training and military support to civilian authorities.

## Insignia

The shoulder sleeve insignia was originally approved for the 78th Infantry Division on 27 May 1922. It was retained for the 78th Division (Training) on 11 Sep 1959. The insignia was redesignated on 1 Oct 1993 for the 78th Division (Exercise) and the description revised to provide metric measurements. The insignia was redesignated for the 78th Division (Training Support) on 17 Oct 1999.

### Distinctive unit insignia

* Description: A gold color metal and enamel device 1+3⁄16 inches (3.0 cm) in height overall, consisting of a white enamel alerion on a scarlet enamel disc centered upon a blue enamel equilateral triangle with notched sides, all in front of two white enamel lightning flashes in a V form contained at top and bottom by a continuous scarlet scroll inscribed below with the word "AUDACITER" in gold.
* Symbolism: The white alerion on scarlet is from the arms of Lorraine Province in France where the organization served in three World War I campaigns. In World War II, the unit participated in the Ardennes-Alsace, Rhineland and Central Europe campaigns indicated by the three points, in the color blue for Infantry and for the area of the Rhine River. The white flashes and the red of the scroll allude to the Division shoulder sleeve insignia.
* Background: The distinctive unit insignia was originally approved for the 78th Division (Training) on 21 Dec 1971. It was redesignated on 1 Oct 1993 for the 78th Division (Exercise) and the description revised to provide metric measurements. On 17 Oct 1999 the insignia was redesignated for the 78th Division (Training Support).
