Change Posture

Characters may crouch or go prone as a free
action. However, a character forced into that
position need to make an effort to stand, which
counts as an action.
Crouching adds 1D to the combat difficulty to hit
the defender or +2D if they are moving (speed
is halved).
Prone targets subtract 2D from the combat
difficulty when attacked at Short range or less,
but add 2D to combat difficulty when attacked at
Medium or Long range.
