Yes, 1970's Leopards are "western wonder weapons" to russians. That's actually a sad comment on the russian military, that a 1970's Leopard tank is better that anything the russians currently have.
Do realize the Ukie Leopards ( and MRAPS and Bradleys, etc) were destroyed before firing a shot, once again attesting to Ivan’s abilities.
Vlad still holds all the cards, and there is nothing the collective West can do about it.
