What advantage in warfare did the hykose use to defeat the Egyptians?

Who were the hykose?

The Hyksos were a group of mixed Semitic peoples who invaded and ruled parts of Egypt during the Second Intermediate Period (around 1650-1550 BCE). They established the 15th Dynasty and controlled the northern regions of Egypt, including the Nile Delta. The name "Hyksos" is derived from an Egyptian term meaning "foreign rulers." Their reign marked significant cultural exchange, but they were eventually expelled by native Egyptian forces, leading to the rise of the New Kingdom.
