Probably not but I think Chobham armor is still classified if that's what the Germans are using on their Leopards given how weak the T90 has proven to be they may decide to reverse engineer that type of armor protection for their tanks.
I'm all for giving the biggest gangster in the world a bloody nose and seeing him off but not contribute anything from the West that may advance his domination on the battlefield.
Russiaicon has never worried one iota about battlefield casualties nor losses they will just keep throwing stuff in there till it gets to inhibitive for the West to maintain the arms flow how many T55 - T72's do they have lying around 10-15000!
How long will it take to build stocks up again after all the OOD ammo is expended and it starts to eat into existing current dated ammo, plus in WWII they estimated Russia lost 20 million souls some estimates have said the number may be as high a 50 million so don't think Putin will just stop because he looses a few Alligators or T90's!
