Fratricide rules

One incident I remembered about fraticide. A friend of mine related a story
about a group of Stukas in WWII orbiting the battlefield and waiting for a
call, when suddenly one of their group vanished. The remainders all went into
evasive manouevers, called for fighter support and tried to see where the
enemy fighters where. Then another stuka vanished. They eventually worked out
that they were in the flight path of an artillery barrage!

Perhaps a random selection of friendly unit to hit? ^_^
