Israel
Even though Israel is a tiny country, it needs to maintain a sound defense system owing to the insurgency in Palestine and the instability in the Middle East. It boasts itself as one of the best forces in the world while it owns and operates some of the most modern equipment in the industry.
While the Israel Defense Forces only employ about 170K active and 465K reserve personnel, not many states can dare confront them owing to their power. An example of their high technology operations, Israel owns an Iron Dome, which is a mobile all-weather air defense system that has been keeping them safe from Hamas missiles.
