What would be the pro equivalent of an imperial knight?

I read somewhere that an park engineer was amazed by an imperial titan ( he thought it was the emperor) and decided that Gork and Mork should have their own versions of these towering god engines.

Considering that Imperial knights are more common than the rarer titans, I think there is a high chance that the orks were impressed by these machines.

si what’s the ork equivalent of a knight if they even have anything simila?
