SEISMIC BOMB

Use this Stratagem in your Movement phase, when an ARCHAEOPTER FUSILAVE model finishes a move.
Select one enemy unit that model moved over this phase (excluding TITANIC units or units that can FLY).
Until the start of your next Movement phase, that enemy unit is shaken. While a unit is shaken:
Halve the Move characteristic of models in that unit.
Halve Advance rolls and charge rolls made for that unit.
