3. China – The Asian Tiger
With more than 22,00,000 number of active soldiers and a whopping $129,272,000,000 military budget, this Asian giant has barely a few contenders to match its might. China has more than 9000 active tanks and close to 3000 aircrafts to back up its military. Its warfare is not fully tested, but military exercises with its neighbors show its potential in the face of adversity.
