Bullfrog

From the information available, the Bullfrog looks to be a infantry transport that can move very fast. As a trade off though, it looks like the Bullfrogs armor will be unable to absorb large amounts of damage. The Bullfrog will have some sort of anti-infantry or anti-air capabilities. However, instead of just transporting units on to a beach and deploying them, the Bullfrog will be able to "shoot" infantry to their destinations such as a beachead.
