Signal Corps (United States Army) - Korean War and Vietnam War

Korean War and Vietnam War

During the Korean War and Vietnam War the Signal Corps operated Officer Candidate Schools initially at Fort Monmouth in 1950–1953, graduating 1,234 officers, and at Fort Gordon in 1965–1968, which produced 2,213 signal officers. (The World War II Signal OCS program at Fort Monmouth, from 1941–1946 graduated 21,033 Signal Corps Officers.)

Modern warfare utilizes three main sorts of Signal soldiers. Some are assigned to specific military bases ("Base Ops"), and they are charged with installation, operation and maintenance of the base communications infrastructure along with hired civilian contracted companies. Others are members of non-Signal Army units, providing communications capability for those with other jobs to accomplish (e.g. infantry, medical, armor, etc.) in much the same way as, say, the unit supply sections, unit clerks, or chemical specialists. The third major sort of Signaleer is one assigned to a Signal unit. That is to say, a unit whose only mission is to provide communications links between the Army units in their area of operations and other signal nodes in further areas served by other Signal units.

Sending radio signals across the vast Pacific Ocean had always been sketchy and unreliable. In August 1964, radio communications across the sea were given a huge boost in quality: The first satellite terminal ever installed in a combat zone was installed in Ba Queo, near Saigon, led by Warrant Officer Jack Inman. This enabled trustworthy communications to Hawaii, and thereby to Washington, D.C.

From north to south, communicating across the varied landscapes of Vietnam presented a variety of challenges, from mountains to jungle. The answer came by utilizing the technology of "troposcatter". A radio signal beamed up into the atmosphere is "bounced" back down to Earth with astonishingly good results, bypassing debilitating terrain. The Army had little experience with this technology, so they contracted the development of the systems to Page Engineering. In January 1962, Secretary of Defense Robert McNamara approved the system of troposcatter units under the operational name of BACKPORCH.

The escalation of the number of troops in the Vietnam War caused an increasing need for more communications infrastructure. In the spring of 1966 the assorted Signal units were reassigned to the newly-formed 1st Signal Brigade. By the close of 1968 this brigade consisted of six Signal groups, and 22 Signal battalions—roughly 23,000 soldiers.

One of the very first Vietnam War Casualties was SP4 James Thomas Davis, a radio operator.
