Ukraine's US-provided Bradley armored fighting vehicles are turning heads in tough battles against Russia

• Ukraine's US-supplied Bradley fighting vehicles have become one of its most important weapons. 
• They're being used for bold attacks, armored combat, and casualty evacuation.
• Limited numbers and new threats in battle mean Ukraine has to improvise.

In a snowy landscape near Stepove in eastern Ukraine, Russian and Ukrainian armored vehicles went head-to-head in what appeared to be a mismatched fight.

In a video released by Ukraine's defense ministry earlier this year, a Russian T-90 tank, once billed by President Vladimir Putin as the world's best, faced off with two Ukrainian 47th Mechanized Brigade Bradley armored vehicles.
