World War One involved a great deal of technical and scientific innovation. War-related research programs brought out weapon technologies such as poison gas, tanks, aircrafts, modern artillery, flame throwers, and submarines as well as technologies that also found civilian uses, for example hydrophones and mobile X-ray stations.
In general, military commanders tended to veto against the filming of innovations relevant to the war effort due to fears of espionage. Technologies that were no longer regarded as secret, however, sometimes were officially presented to representatives of the press and camera operators in order to highlight the innovative capacity of the nation. This was especially true for captured weapons from the enemy, which could be publicly shown without considering secrecy issues.
