Russia: 1.03 million troops, 2.02 million reserves; including 420,000 in the army, 160,000 in the air force, and 150,000 in the navy.
Ukraine: 250,000 troops, 1 million reserves; 210,000 army; 44,000 air force
When it comes to military strength, Russia is slightly superior.

The Russian Army Aviation Corps is mainly equipped with a total of 3,748 helicopters of three types. Including: 1654 combat helicopters, of which 1320 are Mi-24s, 10 Are Mi-28s and 20 are Ka-50s. There are 1400 transport helicopters, of which 80 are Mi-26s.
Ukraine was once the world's fourth-largest air force, with 1,100 warplanes, and only 50 can currently take off with bombs.
The rest, needless to say, is not a level, Russia won.
If Russia clashes with Ukraine, the United States cannot join directly unless it wants to fight a world war. I'm pretty much looking forward to it.
As long as Ukraine does not follow the United States, there is nothing to do, and the United States has been fanning the flames behind its back and constantly provoking incidents, resulting in escalating tensions on the Russian-Ukrainian border, and the war seems to have reached a stage of imminent outbreak. The United States has already begun to send 3,000 American troops to eastern Europe, which is obviously a dangerous signal.
Mainly depends on what Ukraine has done!
