Excalibur shells have long ranges and high precision, but its precision was based off of using GPS guidance and the warzone reports that the use of Russian EW systems reduced their effectiveness to 6% in accurately hitting targets and this is not including the short life of the barrels of the howitzers or the current lack of shells while Russians use laser guidance krasnopol shells which they started to mass produce and have no problems with their shell productions.Some observations by an Ukranian soldier regarding some equipment received, namely that the M777 chews through barrels to the point they can have ammo but can't use the gun as the barrel is busted and replacements are harder to come by than ammo, and that M1's are way too heavy for some of the weather and filters clog easily and often forcing the tank to stop to clean them out.
Ukranians and Reuters claim Russia used KN-23 Hwasong 11 missiles
Western tanks were not modified like with cages or EW systems to deal with this war currently
South Korean F-35 hits a bird in which the repairs cost more than the aircraft they purchased with other issues like pilots self-ejecting or a member from congress such as Gaetz saying of all the F-35s produced more than 2/3rds of them can't fly.
Is western military equipment really made for war? It wouldn't matter if eastern European countries gave Ukraine the brave Ukrainian patriots and they all got converted into being super soldiers like Simo Hayha or Chris Kyle to solve the manpower issue and Russian troops that have been training for months and doing rotations for this war all had the firearm accuracy of Star Wars storm troopers. I have seen too many western mercenaries with go pros with the last footage before it blacks out is when they are under artillery fire running.
