The Church Fathers identified Jews and Judaism with heresy. They saw deviations from Orthodox Christianity as heresies that were essentially Jewish in spirit. Tertullian implied that it was the Jews who most inspired heresy in Christianity: "From the Jew the heretic has accepted guidance in this discussion [that Jesus was not the Christ.]" Saint Peter of Antioch referred to Christians that refused to venerate religious images as having "Jewish minds".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who suggested that it were the Jews that brought dissension into Christianity?
Ah, so.. Tertullian

After World War I the US Army started developing a dual-role (AA/ground) automatic 37 mm cannon, designed by John M. Browning. It was standardised in 1927 as the T9 AA cannon, but trials quickly revealed that it was worthless in the ground role. However, while the shell was a bit light (well under 2 lbs) it had a good effective ceiling and fired 125 rounds per minute; an AA carriage was developed and it entered service in 1939. The Browning 37mm proved prone to jamming, and was eventually replaced in AA units by the Bofors 40 mm. The Bofors had attracted attention from the US Navy, but none were acquired before 1939. Also, in 1931 the US Army worked on a mobile anti-aircraft machine mount on the back of a heavy truck having four .30 caliber water-cooled machine guns and an optical director. It proved unsuccessful and was abandoned.
