Uncertain international security conditions have made the United States begin to prepare for modern war .
Last May 21, the top US general, Mark Milley, addressed Army soldiers about the challenges of modern warfare.
Reporting from VOA News , Mark Milley called on young US officers to be ready for modern warfare with robotic weapons and drones that are currently little seen in the Ukraine crisis.
In his speech, Mark Milley gave a grim picture of a deteriorating and unstable world.
The great powers intend to change the global order in the coming era.
Milley told cadets who had just graduated from the US Military Academy that they would take responsibility for making sure the US was prepared for the conditions.
"The potential for significant international conflict between the great powers is increasing, not decreasing," Milley said .
"Any overcompetition we've felt militarily over the last 70 years will end quickly and the U.S. is in fact already being challenged in every domain of warfare, space, cyberspace, maritime, air, sea and land," continued Mark Milley.
Mark Milley admits that the US today is not an unrivaled global power.
The US is faced with massive economic and military developments from China and Russia.
In addition, there is also the threat of North Korean missiles and unstable conditions in the Middle East and Africa that could threaten the existence of the US.
Based on observations from the Russia-Ukraine wars, Mark Milley said future wars will be very complex with elusive adversaries.
An urban war will emerge that requires precise long-range weapons and new advanced technologies.
In 25 to 30 years later the basic character of the war and its weapons will change.
Milley said that the US military should not just stick to old war concepts and old weapons.
The US must modernize the ancient forces and equipment that could potentially hinder US victory in modern warfare .
Milley told young officers to be ready to fight with tanks, ships, and robotic-based fighter jets.
In addition, young US officers must also be able to lead a war that relies on synthetic fuels, 3-D manufacturing, and human engineering.
