Answer: Due to advances in military industry, soldier training, and technique.
Explanation:
During the ancient period and the Middle Ages, mass military operations were launched to achieve specific military objectives. With the development of science, technology, and advances in the military industry, this practice has diminished. With the training of soldiers, with the development of the technique, smaller military units were organized that numbered significantly fewer soldiers to carry out certain military operations. Fewer well-trained soldiers were more comfortable to coordinate. Also, these troops performed individual tasks faster, and sometimes these operations were crucial to achieving a particular strategic advantage on the battlefield.
The Celts were not an unified state but rather a group of numerous tribes that often didn't even speak the same language. They were found all around Europe and were mostly Warriors who build their societies around kinship. They were good farmers and mostly were common people. They didn't have a strong unified state because they lived day in day out, women would give birth to children and men would work on the land and occasionally fight against invaders. There was no spirit of a great Celtic nation.
