What unit does each rank command?

In military hierarchy, each rank typically commands a specific unit size, which varies by branch and country. For instance, a Lieutenant commands a platoon (about 20-50 soldiers), a Captain leads a company (approximately 100-200 soldiers), a Major oversees a battalion (around 300-1,000 soldiers), and a Colonel commands a brigade (about 1,500-3,000 soldiers). Higher ranks, like General, manage divisions or larger formations, often comprising thousands of troops. The exact size and structure can differ based on the organization and mission requirements.
