The minimum unambiguous citation for this Army Field Manual is: FM 55-8, December 1961
In 1961, American military intelligence was decentralized. The Army was responsible for all intelligence concerning foreign armed forces. Within the Army, the technical services – Transportation Corps, Signal Corps, Ordnance Corps, etc. – were responsible for intelligence concerning analogous organization in foreign organizations. The Transportation Corps was responsible for intelligence concerning foreign transportation equipment and services. Since there was no centralized American military intelligence organization, the Transportation Corps was tasked with supplying intelligence concerning foreign road and rail networks and waterways as well as ports and landing beaches and airfields.
This manual defines transportation intelligence and prescribes Army doctrine concerning training and use of forces in the field to gather information to be used to produce transportation intelligence and for use of transportation intelligence.
