0 did send equipment but there was something wrong with them. I don’t recall the details.
Here is information from Defense News regarding both the Trump aid and comments about previous Obama aid.
“Some of the early nonlethal aid [from Obama] was useful. After Ukraine received 20 Lockheed Martin AN/TPQ-53 radar systems that track incoming mortar and short-range artillery fire in 2015, the casualty rate for units equipped with those system went from 47 percent to about 18 percent, Ordynovych said. “That was some of the most useful equipment that we ever provided them because it provided them early warning,” Hodges said. “The Ukrainians used [the radar] so much, they were under so much rocket and mortar fire, that they became extremely proficient. So we learned from them.”
[We learn from providing equipment to our allies in active warfare situations. This is just like the Germans and Russians learned by providing weapons to the two sides of the Spanish Civil War just before WW2.
