When did the cavalry disband?

Answer 1

The cavalry, as a distinct branch of military service, began to decline in importance with the advent of mechanized warfare in the early 20th century. While some cavalry units were disbanded after World War I, others continued to serve in various capacities throughout the interwar period and into World War II. By the mid-20th century, traditional mounted cavalry was largely disbanded, with the last remnants effectively transitioning into armored or mechanized units. The U.S. Army officially disbanded its last horse cavalry units in 1954.
