The phrase "army subdivision" can be substituted with a number of synonyms, depending on the context. In a military context, "platoon" or "company" might be used to refer to smaller, specialized units within a larger army subdivision. "Battalion" and "regiment" are also commonly used to describe larger subdivisions of the army. "Brigade" and "division" refer to even larger groups of soldiers, with the latter being made up of several brigades. In non-military contexts, terms like "department," "division," and "branch" might be used to refer to specialized areas within a larger organization.
