Ukraine's Counteroffensive Puts Pressure on Russia's Army.

Ukraine is using HIMARS on the front lines to hit Russian positions in the south of the country, according to a prominent Russian war blogger. The U.S. has provided 38 HIMARS to Ukraine in its military aid packages. Questions remain over whether Ukraine has already launched its long-expected counteroffensive push against Russian forces. On Monday, Russia's defense ministry said Ukraine had launched a "large-scale offensive" on Sunday, focusing on "five sectors of the front." However, the head of the Wagner Group of mercenaries fighting in Ukraine, Russian oligarch Yevgeny Prigozhin, said earlier this week that Ukraine's forces "have already broken through the line of defense" in several areas.
