4 HIMARS from US, 4 M270 MLRS from UK, 4 MARS (same thing as M270) from Germany. If they all fire one load of missiles per day, 120 targets will be destroyed.The number of HIMARS and M270 offered is negligible as of now( Us agreed to give 4 units of HIMARS if i remeber correctly). They won't make any difference untill way more of them are offered. French provided 12 Caesar and promised another 6. Those numbers won't make any difference,
There is nothing varified about your claim of 200 or 250 Russians getting killed per day. Almost all neutral observers put Russian casualties at a fraction of those. Ukraine is loosing the artillery battle, war in Ukraine is an artillery battle now.
Who is neutral? NATO estimates aren't much behind Ukrainian ones, about 75% of.
