It does have tanks that are just like the ones in cod3. The dogs are little more than a variation on the attack heli from 4. On one hand it's good that it's similar, but could the developer not have gone their own route instead of just directly ripping what had gone before? There is one thing to be similar but it's just like a re skinning. Smacks of lazy to me. It doesn't feel like a new game at all, more like an expansion pack. Obviously there will be the single player side as well, but I have a nasty feeling that is going to be just another re hash too.
