February 24, 2023, marked the one-year anniversary of Russia's invasion of Ukraine.
Billions of dollars of aid has been sent, and Russia has lost about half its fleet of tanks.
When his troops invaded on February 24, 2022, Russian President Vladimir Putin expected to quickly sweep through the country and capture Kyiv.
Still, the cost of the war — in lives, dollars, and military equipment — has been high.
