Trench Foot

Play this card on another team at the beginning
of a mission. The weather has been particularly
nasty these past few weeks, the trenches are filling
with water and mud, this is a tolerable hell since
your feet soon become numb. Tolerable until
you remove your boots and discover that you
are afflicted with trench foot. The doctors say
they'll need to amputate; for the next challenge
you won't be able to walk.
