Super-Heavy Walker

Each time a unit with this ability makes a normal, advance or fall-back move: 

• Models in that unit can move through models (including MONSTER/VEHICLE models, but excluding TITANIC models) and can move horizontally through sections of terrain features that are 4" or less in height. 
• Before moving that unit, you can select for all models in that unit to have the MOBILE keyword until that move ends. If you do, when that move ends, roll one D6: on a 1, that unit is battle-shocked.  Designer’s Note: Gaining the MOBILE keyword for the duration of a move will enable models in that unit to move horizontally through dense terrain features (13.06).
