Destruction of S-400 Missile Sites on Crimea Accomplished with LONG-RANGE ATACMS, 100 of Which Were Delivered to Ukraine Surreptitiously

Last week, Ukraine used long-range ATACMS missiles delivered in secret to destroy multiple S-400 systems and much more at the Russian airfield in Dzhankoi, occupied Crimea. New York Times reports over 100 such missiles were already delivered to Ukraine before the House vote. 

Kyiv can now strike Russian forces anywhere in occupied Ukrainian territory

Ukraine now has all 3 primary variants
of ATACMS missiles:

165km Cluster ATACMS 

300km Cluster ATACMS 

300km Unitary ATACMS 

 Estimated Stockpile: Over 100 ATACMS 

 And while 100 ATACMS could inflict serious damage to the Russians, the US still has +2,100 ATACMS in reserve. 

I wonder what they could do with 500.
