How was war different in the Ancient Near east compared to modern day warfare?

Soldiers would lunge out in groups to attack the enemy, as few as one man or whole unite such as a Roman maniple. This is where such small unit officers like the centurions were so important, leading from the front they exhorted their men to be brave and attack and often led by example and started the attacks.

Explanation:

Trenches were long, narrow ditches dug into the ground where soldiers lived.

They were very muddy, uncomfortable and the toilets overflowed.

There were many lines of German trenches on one side and many lines of Allied trenches on the other.

i hope these are alright :)
