U.S. Army Aviation
(Original Article Written 12/12/12 by Jim Broumley)

Army Aviation became a separate branch on April 12, 1983, but soldiers had been taking to the air since the days of the observation balloon. Aviation is one of the combat arms branches today, but in the beginning, flying was just a method of observation and scouting. During the American Civil War, both the North and the South used balloons to direct artillery fire and observe enemy dispositions. This marked the beginning of aerial support for ground forces. The United States also used balloons during the Spanish American War and WWI. However, soon after the first powered flight the airplane quickly replaced balloons for all military purposes.

The Wright brothers flew the first heavier-than-air, engine-powered, full-size airplane at Kitty Hawk, North Carolina on December 17, 1903. Within a few years, the leadership of the Army began to run tests of the new invention to see if it had any military benefits. During one of these tests, Lt. Thomas Selfridge became the first U.S. soldier killed in an airplane crash. He had been flying with Orville Wright on September 17, 1908, when the mishap occurred. The following year, the Army accepted delivery of "U.S. Army Aeroplane No. 1," built to specification by the Wright brothers, on August 2, 1909. The subsequent October 26 saw the designation of the first two Army aviators, Lieutenants Frederic E. Humphreys and Frank P. Lahm, when each completed their first solo flight.

With the approval of Congress, an Aviation Section was created under the U.S. Army Signal Corps on July 18, 1914. The Punitive Expedition to Mexico saw the first tactical usage of Army airplanes when General John J. "Blackjack" Pershing used them for scouting while the expedition chased Pancho Villa's forces in northern Mexico. Nevertheless, the Army only had a few dozen aircraft in the inventory when the First World War began. During WWI, the number of Army aircraft grew to more than 11,000 planes with more than 190,000 aviation personnel in the Army Air Service, created in May 1918.

After WWI, the leadership of the Army Air Service, particularly General William "Billy" Mitchell, argued forcefully for the creation of an independent air force, separate from the ground forces of the Army. That argument was rejected at the time, but it was evident that aviation needed to be considered a combat arm unto itself. Again with the required action of Congress, the Army Air Service was changed to the Army Air Corps on July 1, 1926, with a newly designated "Secretary of War for Air" to manage it. This action put the Air Corps in equal status with the infantry, cavalry, and artillery.

During the 1930s the top leadership of the Army Air Corps was focusing on the potential for air power to be employed as a strategic asset (in other words, bombing major targets rather than supporting ground units). This concerned ground forces commanders, particularly in the artillery branch that benefited from using light observation aircraft for adjustment of indirect fire. The Army experimented with organic light aircraft in artillery units during maneuvers in 1940 and 1941. The tests of these "Grasshoppers," as the light planes were called, were very successful. Their performance was better than the larger Air Corps planes that had been used previously.

In the meantime, the advance of technology marched on. In January 1938 the War Department disbursed $2 million for research into the possibility of developing rotary-wing aircraft. The Army acquired its first real helicopter on November 1, 1941, a Sikorsky YR-4.

On June 6, 1942, the Air Corps was elevated to the Army Air Forces (AAF), which put that component of the Army on the same level as the Army Ground Forces. The Field Artillery branch was allowed to keep "organic army aviation" under its control. This meant that light observation aircraft like the L-4 Grasshopper and the L-5 Sentinel and their personnel were organic to the artillery battalions and brigades that they worked for. The Department of Air Training was established at the Field Artillery School at Fort Sill, Oklahoma. This date, June 6, 1942, is recognized as the birth date of Army Aviation.

Organic Army Aviation first participated in combat during Operation Torch in November 1942 in North Africa. While the original function of organic Army Aviation was to adjust artillery, during the course of the war, it expanded. During World War II, L-4 Grasshoppers and a few larger L-5 Sentinels were used to adjust artillery fire, gather intelligence, support naval gunfire, conduct medical evacuations (MEDEVAC), and perform other functions like command and control. The expanding mission and close coordination with ground forces were primarily because the aircraft were available to, and often under the command of, the commander on the ground where the assets of the Army Air Forces were not.

The difference in need, mission, priorities, and philosophy as to the employment of aviation assets caused a great deal of friction between the leaders of the Army Air Forces and Army Ground Forces. It was time to separate the two. The United States Air Force (USAF) became its own branch of service, separate from the United States Army, on September 18, 1947. There continued to be a great deal of friction between the services with suspicion of overlapping areas of responsibility and competition for precious funding. On April 21, 1948, President Eisenhower signed the "Key West Agreement" that provided for the division of assets between the Armed Services. Under the agreement, the Air Force would have control of all strategic air assets as well as most tactical aviation and logistic functions. The Army was allowed to retain aviation assets to be used for reconnaissance and medical evacuation purposes. The Navy could have its own combat air arm to support naval operations, which included combat aircraft to support the Marine Corps. After the adoption of the Key West Agreement, the Army continued to develop its light planes and rotary-wing aircraft to support its ground operations. In 1949 the Army established the Warrant Officer Pilot Program to fly new cargo helicopters it was fielding.

The Korean War saw a leap forward in Army Aviation. On January 3, 1951, the first combat medical evacuation by helicopter was conducted - in Korea by 1LT Willis G. Strawn and 1LT Joseph L. Bowler. The H-13 Sioux rotary wing aircraft had been fielded since 1947 and was used for MEDEVAC and command and control operations. The helicopter proved its worth in the rugged terrain of Korea. This recognition of the capabilities of rotary-wing aircraft increased the demand for machines and pilots. In 1951 the Army began organizing helicopter transport companies and the fielding of H-19 Chickasaw, albeit in limited numbers due to the competition for the aircraft from the Air Force.

Forward-thinking leaders in the Army saw the potential of rotary wing aviation. General James Gavin published an article in April of 1954 titled "Cavalry, and I Don't Mean Horses." In this influential article, Gavin called for the use of helicopters in cavalry operations that would provide the mobility that the Army lacked in Korea due to the terrain. This was an indicator of a doctrinal push that rapidly expanded Army Aviation into the combat arm it is today. On November 1, 1954, the Army Aviation School was moved from Fort Sill to Fort Rucker, Alabama. The United States Army Aviation Center (USAAVNC) was established there in March 1955.

Under this new doctrine of "air cavalry," the Army saw the need to mount weapons on helicopters to serve as a kind of "aerial artillery." The French Army had seen some success mounting rocket launchers and 20-mm cannons on helicopters during the Algerian War of 1954-1962. Based on this example, the Army began running tests on armament systems for rotary-wing aircraft in 1956. Primarily, Colonel Jay D. Vanderpool directed these combat development experiments. Vanderpool also wrote the first doctrinal manuals. This research and development was conducted while the Air Force still theoretically had exclusive responsibility for aerial fire support. Nevertheless, Army commanders felt that the Air Force was not doing enough to prepare to support ground forces and under the Key West Agreement were not allowed to arm their fixed-wing aircraft. Therefore, it would seem that competition between the services actually led to the development of armament systems for Army helicopters.

An armed helicopter company was activated in Okinawa in 1962 and later deployed to Thailand and then Vietnam. In Vietnam, the new helicopter company flew escort for lift helicopters. There were no mission restrictions on the army aircraft enforced by the Department of Defense, thereby giving implied permission to deploy armed rotary wing aircraft. Also in 1962, the Tactical Mobility Requirements Board was formed. Commonly known as "The Howze Board," this group had been established to develop and test the concept of air mobility. After test exercises, war games, and concentrated study and analysis, the Howze Board recommended that the Army commit itself to organic air mobility through the extensive use of helicopters. The 11th Air Assault Division (Test) put the Board's recommendations into testing from 1963 to 1965. Beginning with their deployment to Vietnam in 1965, the 1st Cavalry Division (Airmobile) repeatedly demonstrated the validity of the airmobile concept in combat. On April 6, 1966, the Johnson-McConnell agreement was signed between the Army and the Air Force. The Army gave up its fixed-wing tactical airlift aircraft (primarily the DHC-4 Caribou) in exchange for the Air Force relinquishing its claim to most forms of rotary-wing aircraft.

Vietnam was truly America's "Helicopter War." The United States' involvement in Vietnam began with Army Aviation operating a fleet of reciprocating engine aircraft. In the early days of the development of air mobility, the UH-1 Iroquois, or Huey was introduced, a modern turbine-powered aircraft with both troop carrier and gunship versions developed specifically with deployment to southeast Asia in mind. Before the end of the Vietnam War, more than 5,000 of these truly versatile aircraft were sent overseas. Also during Vietnam, the OH-6 Cayuse (the "Loach") and the OH-58 Kiowa were fielded as scout aircraft, replacing the OH-13. In 1967, the AH-1G Cobra came online to begin replacing the Huey gunships as an attack aircraft. The U.S. Army's heavy lift helicopter in Vietnam (and ever since) was the tandem rotor Boeing CH-47 Chinook, introduced in 1962. The OV-1 Mohawk and U-21 Ute (Beechcraft King Air) were part of the small fixed-wing aircraft inventory flown by the Army.

After United States combat forces left Vietnam, Army Aviation continued to develop and pass major milestones. On June 4, 1974, Fort Rucker graduated the first female Army aviator, 2LT Sally D. Woolfolk (Murphy) from Rotary Wing Flight School. NASA chose Major Robert L. Stewart to be the first Army aviator to become an astronaut in January 1978. The aircraft inventory began to enter the modern era with the delivery of the first UH-60 Blackhawk to Fort Rucker on April 1, 1979. In recognition of the demonstrated increasing importance of aviation in Army doctrine and operations, Aviation became the fifteenth basic branch of the Army on April 12, 1983. Since then, commissioned officer pilots would be branched aviation, fully dedicated to learning its operations and tactics, rather than being temporarily detailed from another branch. The Army began to field the AH-64 Apache in 1984. On May 16, 1990, the 160th Aviation Battalion was reorganized and designated the 160th Special Operations Aviation Regiment (Airborne). The unit was assigned to the U.S. Army Special Operations Command and signaled the arrival of dedicated aviation assets to special operations.

Since Vietnam and during operations in Grenada, Panama, and the Persian Gulf Army Aviation has played a major role in combat and support operations. An Army aviator fired the first shot of Operation Desert Storm from an Army helicopter. Within a few minutes, two teams of Apaches destroyed two Iraqi radar stations on January 17, 1991. During the next 100 hours of ground combat, Army aviation dominated night operations. The Army can be justly proud of the performance of its aviation assets and personnel during Desert Shield/Desert Storm, Operation Iraqi Freedom in Iraq, and Operation Enduring Freedom in Afghanistan.

In April 1993, attack pilot positions were opened to female aviators. Another milestone was reached when Lieutenant Colonel Nancy J. Currie (formerly Nancy Sherlock), the first female Army aviator to become an astronaut, made her first space flight on June 23, 1993. By 1998 the AH-64D Longbow was arriving at Fort Hood, Texas. In December 2006 the Army accepted its first UH-72A Lakota, a twin-engine light utility helicopter long overdue in the inventory.

The mission of Army Aviation is to find, fix, and destroy the enemy through fire and maneuver; and to provide combat, combat support (CS), and combat service support (CSS) in coordinated operations as an integral member of the combined arms team. Army Aviation has the organic flexibility, versatility, and assets to fulfill a variety of maneuver, CS, and CSS roles and functions. These cover the spectrum of combined arms operations. Aviation can accomplish each of these roles during offensive or defensive operations and also for joint, combined, contingency, or special operations. Since its inception over one hundred years ago, Army Aviation has continued to modernize. With the integration of the AH-64D Longbow, MH-47E, MH-60K, and the UH-72A Lakota, Army Aviation stands on the threshold of a new century more mission capable than ever.

The Americal Division
(Original article written 5/3/2010 by Jim Broumley)

The U.S. Army's 23rd Infantry Division, more commonly known as the Americal Division, was "born in battle" in that the division was formed in the Pacific Theater during World War II. On April 19, 1942, the 164th Infantry Regiment and additional artillery assets arrived on the island of New Caledonia to reinforce the 132nd and 182nd Infantry Regiments already there. This task force was reorganized as an infantry division and given the name "Americal" on May 24, 1942. The name was taken from the phrase "Americans in New Caledonia" and at that time was the only American division without a numerical designation.

The 164th Infantry Regiment of the Americal Division fought on Guadalcanal beginning on October 13, 1942, alongside the 1st Marine Division. This action made the 164th and thus the Americal, the first United States Army unit to conduct an offensive operation against the enemy in either the Pacific or European Theater of Operations. (Seven other U.S. Army divisions began offensive combat operations in late 1942: the 32nd and the 41st Infantry Divisions in New Guinea; the 9th and 3rd Infantry Divisions, and the 2nd Armored Division in North Africa.) Elements of the Americal defended Henderson Field against heavy enemy attacks, 23-25 October, took part in the offensive across the Matanikau River in November, and attacked and took Mount Austen in January 1943. Once organized resistance ended, the Americal was relieved on February 9th.

The Division moved to the Fiji Islands beginning on March 5, 1943. The Americal was given the mission of defending Viti Levu Island in the Fiji group, a vital communications link between the United States and the Pacific theater. The division used the time to train its replacements for upcoming operations. The rest of 1943 was spent operating observation posts, running continuous reconnaissance patrols, and training.

The Americal Division fought on Bougainville from December 25, 1943, to January 12, 1944. They had relieved the 3rd Marine Division and were given the task of holding and extending the right half of a previously established perimeter. The Americal Division conducted an offensive in March of 1944 that drove the Japanese east of the Mavavia River. By the end of April, they had seized numerous strategic hill bases. Training and long-range patrol activity continued until November 30, 1944, when the Division was relieved.

On January 8, 1945, the first units of the Americal Division left Bougainville, heading for the Philippine Islands. Americans had already established strong points in the Philippines in the campaign to recapture the islands. The Americal was now being attached to X Corps on the island of Leyte. Their mission on Leyte and Samar was to take part in cleaning out the remaining Japanese forces on those islands. Additionally, the Division was to invade Biri, Capul, Ticao, and Burias. The Americal was relieved on Leyte on March 13, 1945. The Division then landed on Cebu on March 26th and seized the city and airfield two days later. Divisional combat teams made landings on Bohol, Negros, and Mindanao, where they cleared out pockets of resisting Japanese until June 17th, when ordered to return to Cebu.

Training continued on Cebu for the proposed invasion of Japan. However, the Japanese surrender on August 14, 1945, thankfully made this operation unnecessary. On September 10, 1945, the Americal Division landed in Japan and took part in the occupation of the Yokohama-Kawasaki-Yokosuka area.

The Division returned to the United States on November 21, 1945, and was inactivated on December 12, 1945. The Americal was reactivated on December 1, 1954, and finally given a numerical designation as the 23rd Infantry Division. However, they retained the name "Americal" as part of its official designation. The 23rd Infantry Division served in the Panama Canal Zone until April 10, 1956, when it was again inactivated.

The 23rd Infantry Division, Americal, was reactivated again in 1967 in the jungles of Vietnam. Now they traced their roots to Task Force Oregon which operated in the I Corps area of operations that included Chu Lai, Quang Ngai Province, and Duc Pho. Task Force Oregon originally consisted of the 196th Light Infantry Brigade, the 1st Brigade of the 101st Airborne Division, and the 3rd Brigade of the 25th Infantry Division, which was later redesignated as the 3rd Brigade of the 4th Infantry Division. The task force became operational on April 20, 1967. Their early Operations included Malheur I and Malheur II, Hood River, Benton, and Cook.

Operation Wheeler was launched on September 11th against elements of the 2nd North Vietnamese Army Division in an area northwest of Chu Lai. On September 25, 1967, Task Force Oregon was designated as the Americal Division. The division was created from the 196th, 198th, and 11th Light Infantry Brigades. Operation Wheeler continued until October 4th when the Americal was joined by 3rd Brigade 1st Air Cavalry Division and Operation Wallowa was launched into the northern sector of the Americal's area of operations. Operations Wheeler and Wallowa were combined on November 11th.

The Americal, 23rd Infantry Division, continued to serve with distinction for the remainder of American combat operations in Vietnam. Twelve Americal soldiers were recipients of the Medal of Honor during the Vietnam War. Several subordinate elements of the Americal Division were awarded Presidential Unit Citations and Valorous Unit Citations in addition to multiple awards for valor from the Vietnamese government. Noteworthy persons who wore the Americal patch include General H. Norman Schwarzkopf, General Colin Powell, and former Governor of Pennsylvania and Secretary of Homeland Security Tom Ridge.

Unfortunately, the 23rd Infantry Division, Americal's reputation has been permanently scarred by what is known as the My Lai Massacre. On March 16, 1968, C Company, 1st Battalion 20th Infantry Regiment, one of the companies of the 11th Light Infantry Brigade, with 2nd Lieutenant William Calley as a platoon leader, was responsible for the murder of 347 to 504 unarmed Vietnamese citizens, all of whom were non-combatants. Lt. Calley and his company commander, Captain Ernest Medina, were prosecuted by court martial for the offenses at My Lai. While 26 U.S. soldiers were initially charged with criminal offenses for their actions at My Lai, only Lt. Calley was convicted. He served only three years of an original life sentence, while on house arrest. When the incident became public knowledge in 1969, it prompted widespread outrage around the world. The massacre also increased domestic opposition to the US involvement in the Vietnam War.

The 198th and 11th Infantry Brigades were withdrawn from Vietnam in November 1971. The Americal Division was inactivated at that time. The 196th Light Infantry Brigade was reconstituted as a separate brigade and remained in Vietnam until June 29, 1972. The 196th Infantry Brigade was the last major combat unit to leave Vietnam. Its 3rd Battalion, 21st Infantry Regiment, was the last U.S. maneuver battalion to leave Vietnam, on August 23, 1972.

The shoulder sleeve insignia of the 23rd Infantry Division was originally approved for the Americal on December 20, 1943. The patch's four white stars on a blue field are symbolic of the Southern Cross under which the organization has served. The blue color stands for infantry. Many men have served "Under the Southern Cross" with pride, courage, and professionalism, defeating the enemy in each encounter from New Caledonia to Vietnam.
