These are the ten most powerful militaries in the world
Each year, the website Global Firepower ranks countries in what they call the "global firepower index," a ranking of the world's 126 most powerful militaries. The index uses a 50-point algorithm to determine a nation's military power. Their system focuses on the diversity of weapons systems and provides bonuses and penalties for things like nuclear arms, diversity of force structures, and alliances (like NATO). The formula is interesting because it makes a smaller but more technologically advanced country competitive with larger militaries from less advanced countries.
