Crusher Stampede

Each time a TYRANIDS MONSTER model from your army makes an attack, add 1 to the Hit roll if that model’s unit is below its Starting Strength, and add 1 to the Wound roll as well if that model’s unit is Below Half-strength. In addition, while a TYRANIDS MONSTER unit from your army (excluding Battle-shocked units) is at its Starting Strength, add 2 to the Objective Control characteristic of models in that unit.
