Final answer:
The British introduced the tank during World War I, in 1916, as a new type of military technology to support infantry and attempt to end the stalemate of trench warfare.
Step-by-step explanation:
The new type of military technology introduced by the British during World War I was the tank. In 1916, the British military leveraged the technological advances of the early twentieth century to unveil a new weapon to support their infantry—the tank. These early tanks served to make large artillery mobile and could travel alongside advancing infantry, contributing to an effort to break the stalemate of trench warfare, although they frequently malfunctioned and had issues with difficult terrain.
World War I was characterized by prolonged trench warfare and saw the introduction of mechanized warfare with weapons such as tanks, machine guns, long-range artillery, and airplanes. The utilization of these new military technologies resulted in massive casualties and little territorial gain, highlighting the brutality and stalemate of the conflict.
