Ukrainian forces prepared their defenses on March 24, 2022, by digging trenches and keeping watch, anti-tank weapons and machine guns at the ready. READ MORE: Western defense officials say Ukraine has been employing agile insurgency tactics to disrupt Russia's invasion, and in the suburbs northwest and east of Kyiv, to push their adversaries back. Hitting and ambushing Russian forces behind the contact lines with fast-moving units, often at night, have proved to be among its most effective field tactics and is adding to the logistical missteps the Russians still have not been able to overcome, military strategists say. They add that the tactics are also demoralizing Russian troops. "They're doing a tremendous job," said Colonel John Barranco of the Atlantic Council, a New York-based think tank. "The Ukrainians have developed a very competent military with good leadership at the lower level and they're motivated. And this is why, when I looked at the Russian forces deployed for the invasion, I thought, this doesn't seem like a well-thought-out effort."
