Pay 4 Force Choose one of your opponent's units in the Ground or Character arena. If your opponent rolled no hits for that unit's last attack, he or she discards that unit. Play only after that unit has attacked and before any other unit attacks.
No dice are rolled for a unit with 0 power, so your opponent rolls no hits for such a unit.
You can play this card only if your opponent rolled no hits. If your opponent rolled any hits but the damage was prevented, this card still can't be played.
If the defending unit is removed from battle after the attack begins, but before the dice are rolled, then no hits are rolled. Rebel Surrender is a valid play in this instance.
Armor can cause the attacking unit to be discarded on a roll of 4 when Rebel Surrender is played. Accuracy can affect this chance.
