Lancets and Geran-1-2 (Shaheds) loitering munitions are there to take care of western tanks. One Shahed variant costs around 20,000 dollar, while one Challenger-2 MBT costs almost 4,500,000 dollar.
Ukraine in some cases could hide artillery systems such as M-777 using camouflage methods but despite that, loitering munitions detected them and destroyed them. How can they hide an MBT as big as Challenger-2 in the open battlefield, a tank supposed to slowly advance into the enemy controlled territories, specially, considering the fact that it is Ukraine that has lost lands hence they are the ones supposed to be the advancing force?
West specially Europe knows that Ukraine is a lost cause but they are still paddling in self made swamp.
