1. Chile
Chile might not have the largest army in South America, yet it is by far the most advanced in the region. This is largely due to the fact that legislation from the Pinochet era continues to guarantee income from copper exports be dedicated exclusively to the military. Hence, over the years, Chile has been able to acquire 118 Leopard 2 tanks from Germany, 28 F-16s, and even eight French/British-made frigates, and develop the most technologically sophisticated army in the region.
