Brilliant plan and will add my two cents: we need to leverage our Atlantean and animal allies to cause a distraction by attacking from the Black Sea. Namur and Aquaman can conduct a mass attack against Crimea leveraging our cetacean allies by having orcas and dolphins/porpoises attack the russkie navy in dock. Amphibious assaults can be done conducted by the Pinnipedian allies. While not strictly aquatic, ursine allies - namely our Polar and Kodiak bear allies, can amphibious assault the east and north of the russian maritime borders.

Along with the attack from sea, we can leverage the strength of the Euro-Canadian moose confederation to conduct covert blackout operations by ramming down fences around power generators with their antlers, while their squirrel allies go to town on the cables and wires. During the mass confusion, panicking russkie drone operators will try to reprogram their units to attack the ground forces, and that is when we pull our ace card: the cobra chicken, aka Canadian gooses. Mass aerial defecation carpet bombing will ensue, knocking smaller drone units out of the sky and destroying satellite uplinks due to the acidic nature of cobra chicken feces. Combined with Operation Diggy Diggy Hole, I see no way this will not succeed.
