Over the weekend of April 27, Ukrainian troops were on the retreat from Russian forces. The United States is rushing aid to Ukraine since the foreign aid package passed on April 24. However, Ukrainian President Volodymyr Zelenskyy said the weapons coming from the U.S. need to come faster because Russia is capitalizing on the holding period.

Zelenskyy said the aid is urgent since Russia’s artillery shells outnumber Ukraine’s 10 to one.

Ukraine’s shortfalls on the battlefield range from manpower to artillery. Russia is taking advantage, advancing through at least half a dozen villages since February following a capture in the critical town of Avdiivka, which was once held by Ukraine.

Russian President Vladimir Putin is on the offensive. Ukraine is pulling back its line of defense as Ukrainian troops were ordered to retreat from multiple villages.
