1 patriot battery consists of radar stations, command station, and multiple patriot launchers. 1 battery is enough to decently cover a city like kiev
I’ve replied to this type of comment before. NL is such a small country with a high density but low population but very interconnected. I worked at an advertising company in Amsterdam when this happened after leaving a large multinational. I will tell you everyone knew someone or a family who was directly affected by this event. 
It was a very hard time for a lot of people. 
Sterkte allemaal. >

It is certainly not too late! And the US training program, from what I understand is being fast tracked. 
I am super happy the Dutch are doing this. The American donation of the first system plus the training was great news last month, but Ukraine needs a few more Patriot systems, if possible, to cover more of its cities and metro areas that have become Russian (illegal) targets. 
Well done, Netherlands! 👍 >

And IIRC there's a German battery on the way too. >

That is fantastic! I really hope you are remembering that correctly, because it would be excellent news! 
I think I read somewhere that the optimum number would be 8 patriot systems. So if they were to have three already, that would be very good news indeed. They could get the training done and get 3 patriots deployed, and then start training for the next round, which is sure to come either from other countries or more from the US. 
I think the West is disgusted by all the news stories of civilian targets being deliberately struck with large numbers of civilian casualties. I don’t know what Putin expected when he started deliberately targeting civilians in their sleep, but patriot systems should have totally been the expected response. >

One battery requires a team of 90 to operate. >

Holy smokes! What do they all do?
