[Suggestion] A cross land/sea ship

i was thinking more of using a bot-shield wall type of analogy where you send huge death-ball's of them to soak-up enemy fire during naval assaults while the big guns sit in the back but the walking boat has little armor so that it's the number of units in the death ball that soak's up the fire rather than the armor on the unit

What if the boat drove up fast to the coast then jumped a couple of meters into the land then was stuck there until an air transport or astrea picked it up and placed it back to the water.

we could always strap a bomb to a fast amphibious chassis and send it flying at the enemy
