The Russo-Ukrainian War is not over, but the gap between the top three military forces in the world has been repeatedly widened. The Russian military has exposed many gaps in actual combat, including intelligence, long-range precision strikes, air combat and air raids, joint operations, tactical literacy of non-commissioned officers, supplies, overall planning, organization and command.
Before the war between Russia and Ukraine, the US military knew the deployment of the Russian army and could even predict the approximate date of the Russian attack. After the start of the war, the response of the Ukrainian army proved that the Russian army's combat plan had long been mastered, and the Ukrainian army made targeted deployment in advance and matured the use of ambush tactics. The US military should continue to provide accurate information, so that the Ukrainian army knows itself, preserves its strength, and organizes effective resistance.
The US military's satellite reconnaissance capability is second to none in the world; the US military's reconnaissance aircraft stationed in Eastern Europe should be of great use, and they can fully monitor the dynamics of the battlefield without entering Ukraine.
The Russian army has been stationed on the Ukrainian border for more than two months, but it has never been able to detect the real movement of the Ukrainian army. The Russian armored forces made a massive advance and quickly reached the outskirts of Kiev, but did not encounter any main force of the Ukrainian army. Until now, after the Russian army has suffered repeated blows, it still does not know where the main force of the Ukrainian army is.
Russian satellites also do not seem to be functioning, may be interfered with by the US military, Russian reconnaissance aircraft or did not move, or lack of reconnaissance capabilities.
The U.S. military's intelligence on the battlefield reflects its global combat capabilities, compared to the Russian military's difficulty in dealing with a regional war.
