Portable Wall

Overview
The Portable Wall is a new vehicle introduced in the 2.7 patch. It costs the same as a Heavy Tank, and has a whopping 600 and 12! This beast, thankfully, does not cost, but you may only put two on a battlefield at a time. Build it now in your Vehicle Factory if you're level 35+.

Trivia
The Portable Wall looks a Mini Tank struck by a meteor.

You only need a Level 1 Vehicle Factory to build this.
