ZAPORIZHZHIA, UKRAINE - 2024/05/16: Ukrainian servicemen of mobile air defence unit of Ukraine's 141st separate infantry brigade guard with their heavy machine gun Browning M2 on the Humvee (High Mobility Multipurpose Wheeled Vehicle) on duty in Zaporizhzhia region. The effectiveness of Russian missile strikes on Ukraine has seen a dramatic spike recently as Ukraine's ammunition for its air defense systems dwindled due to delay in aid. Russia has ramped up its shelling and used more ballistic missiles to take advantage of Ukraine's lack of ammunition for its Patriot air defense systems. Russia often uses the cheaply produced drones to test air defenses before launching its multi-million-dollar missiles. (Photo by Andriy Andriyenko/SOPA Images/LightRocket via Getty Images)
