The technology advantage and the military tactics employed by the Hyksos include:
Composite bow: The Hyksos introduced the composite bow, a more powerful and accurate weapon than the bows previously used by the Egyptians. The composite bow was made from a combination of wood, horn, and sinew, and could shoot arrows over longer distances with greater force.
Horse-drawn chariots: The Hyksos were also skilled in the use of horse-drawn chariots. Chariots allowed the Hyksos to move quickly across the battlefield and to launch devastating attacks from a distance. The Egyptians had previously relied on infantry and chariots pulled by oxen, which were slower and less maneuverable.
Advanced metallurgy: The Hyksos were also more advanced in metallurgy than the Egyptians, and were able to produce stronger and sharper weapons. They used bronze, a harder metal than copper, for their weapons, while the Egyptians were still using copper.
Military organization: The Hyksos were also highly skilled in military organization and discipline. They were able to field larger and more disciplined armies than the Egyptians, and were able to use their superior tactics and technology to great effect.
Cultural assimilation: Finally, the Hyksos were able to defeat Egypt in part through cultural assimilation. They adopted many Egyptian customs and traditions, and were able to integrate themselves into Egyptian society. This helped to undermine Egyptian resistance and made it more difficult for the Egyptians to unite against them.
