The Ukrainians do operate those Patriots. You have no basis for saying otherwise.
“Multiple” is 2 launcher units out of the 22 delivered to Ukraine. 18 in three batteries and four extra. A Patriot battery is made up of, normally, 6 launchers, a radar vehicle, antenna, control and generator vehicles. The hard to replace bits are these.
And then there are the reload vehicles, Im not sure of the numbers per battery. Some sources say the lost Patriot units in the incident were a launcher and a reload vehicle, which rather resembles a launcher.
That will really help feed your blood lust.
