Other anti Kaiju weapons ?

Yeah I wondered how they knew to automatically make giant man controlled robots. I thought of a process involving other vehicle creations first and seeing what worked and what didn't. And then finally putting all that knowledge into creating the Jaeger program. Plus it would just be great to see cool new vehicles.

Look closely at the screen cap showing what appears to be an aerial view of a Shatterdome. To the right you see what appears to be a row of gigantic tanks.

You can also see those turret in Striker Eureka's art. And they look a lot bigger then the Jeagers.
