The later Roman army was made up of eight (in the early republic, ten) soldiers per contubernium, which shared a tent and ate together. There were ten contubernia in a century. These numbers seem awfully familiar.

Modern armies share structure that is essentially identical. Section/Squad (8-10) -> Platoon (30-40) -> Company (100-120)
