Desperate Breakout

Your Movement phase. Select unit that has
not moved this phase and is in Engagement
Range with enemy unit. Roll 1D6 for each
model; for each 1, one model is destroyed.
If the unit was no destroyed, it can attempt
to Fall Back, its models can move across
enemy models. Any models that end its
move within 1" of any enemy model is
destroyed. If the unit survives, it cannot
do anything else even if it has a rule that
would allow it to do so.
