The Infantry is the oldest and most numerous of the Combat Arms in the armed forces, and consists of soldiers who predominantly fight on foot; an infantry soldier is an infantryman. Infantry units are the only types of land forces that can occupy and hold positions, and therefore have the most physically demanding training in the army, emphasizing physical fitness, physical strength, and aggressive character due to non-reliance on technology that augments marching all of which are required due to the primary role of the infantry to engage in ground combat.
Infantry can be distinguished from other types of soldiers: cavalry, tanks, technicians such as armor and signaler. Nonetheless basic infantry skills are fundamental to the training of any soldier, and soldiers of any branch of an army are expected to serve as auxiliary infantry (i.e. patrol and fight on foot) when necessary.
Although the term infantry dates from the 15th century, the foot troops of the previous eras in history who fought with a variety of weapons before the introduction of the firearms are also referred to as infantry. During the Ancient and Middle Ages Infantry were categorized by the types of weapons and armor they used, such as heavy, medium, and light infantry. Since the introduction of firearms classifications have changed initially to reflect their formations on the battlefield as line infantry, and later to reflect modes of transport and type of tactics used by specific units as Mechanized Infantry or Airborne Infantry.
Since the end of the Second World War infantry became a minority in armies of the Western World, constituting typically between 10% and 30%. This reflects the greatly increased requirement for technical and logistical specialists in Western armies, resulting from the increasing complexity of military technology and equipment and an increased recognition of the importance of logistics in warfare. In the Third World armies, infantry still accounts for a majority of the soldiers.
Infantry is arguably the most flexible of the Combat Arms, able to maneuver in terrain inaccessible to cavalry or armor, and employing infantry support weapons that can provide impromptu substitute for the artillery.


The 138th Infantry has a long and storied history, from the early days of our state through the internal trying time of our country where Brother fought Brother, through the War to end all Wars, through World War II, through the Cold War, and into the War on Terror.

The unit was born in 1832 when it was organized as a volunteer militia company known as the St. Louis Grays under the command of Captain Alton R. Easton. Several years later, the Grays combined with other volunteer companies to form a regiment of the St. Louis Militia.HistoricalInfantry
War Service came in the Mexican War in 1846 when the Grays and a number of other colorfully named units, including the Native American Rangers, Missouri Fusiliers, and Boon Guards were called into Federal Service. They fought in two battles, New Mexico and Chihuahua, before being mustered out in 1848.

In 1852, the St. Louis Grays, in company with the Black Plume Riflemen, Continental Rangers, Missouri Dragoons, St. Louis Lancers, and other units, became the 1st Missouri Regiment. A year later, the Grays had expanded enough to become the 1st Battalion of the regiment.

The 1st Regiment fought in the Confederate Army during the Civil War and saw action at the battles of Shiloh, Mississippi River, Vicksburg, Atlanta, Nashville, Mississippi, Louisiana, Alabama (1864), and Alabama (1865).

At the end of the war, the units were re-formed into independent companies until 1877. In 1878, the St. Louis National Guard battalion was formed and entered state service. It later expanded to the 1st Infantry Regiment of the National Guard of Missouri.

The regiment was mustered into Federal Service for the Spanish-American War in 1898, but didn't leave the United States. In 1916, the unit served along the Mexican border, and in March 1917, was called into Federal Service for the First World War. On October 1, 1917, the unit was designated the 138th Infantry Regiment of the 35th Division.

The next two hectic years found the 138th in some of the heaviest fighting of the war-- the unit participated in the Meuse-Argonne, Alsace, and Loraine campaigns. The 138th had 2 Medal Of Honor (MOH) recipients during World War I; CPT Alexander Skinker and Private Nels Wold. From 1921 to 1940, the 138th served as component unit of the 35th Division and the Missouri National Guard.

When war clouds gathered in 1940, the 138th was called to federal service in December for intensive training. In February 1942, the regiment was relieved from assignment to the 35th Division and saw duty in the Aleutian Islands during that campaign. It was deactivated in July 1944 and was reformed in 1946 and again assigned to the 35th Infantry Division.

During its service in six different wars, the 138th Infantry Regiment has received thirteen battle streamers for action in Mexico, the Civil War, World War I and World War II.

In 1974, the 138th Infantry Regiment was converted and redesignated as the 1138th Engineer Battalion with separate line companies. Many years later, the 1138th became a non-organic battalion and mobilized and deployed for Operation Iraqi Freedom I in May of 2003. The battalion returned in 2004 and was subsequently deactivated in 2005 during the Army's Transformation.

The phoenix denotes the transformation and rebirth of the routine functional brigades to the single multifunctional brigade headquarters. Dark blue, the color traditionally used by Infantry units, signifies the 110th Combat Support Brigade's lineage to the Third Missouri Infantry Regiment; red and white allude to the unit's direct lineage to the 110th Engineer Battalion. The stars symbolize the three basic missions of the Brigade: to enable, to enhance, and protect.
