So far the exchange rate seems to be about four drones per tank. Even with anti drone cover (think chicken wire screens a few feet above the top armor) - armor that isn’t moving is proving surprisingly easy to kill with drones no matter if the armor is Russian or Ukrainian. A 5 kilo payload of thermite ignited above the turret seems to do a surprisingly good job, burning through the chicken wire and dropping down onto the top of the turret and eventually melting it’s way through. And it’s hard to keep tanks moving - what with a fuel consumption more easily measured in gallons per mile than miles per gallon. Especially in mud, and Ukraine’s ‘mud season’s are notorious. Quite possibly, the era of tank warfare is drawing to a close. Possibly still useful in defense in a camouflaged position, but less so on offense. As an armor buddy of mine is fond of saying, “A tank can’t really sneak up on anybody.”
