Ramming (p. 26)
     When one character rams or smashes intentionally into a target (or unintentionally as a result of a coincidental hit due to a miss), it will typically cause damage to both combatants.  This can be done by a character (or vehicle) traveling (running, driving, flying, swimming, etc.) at least 5” toward the target and moving at a speed of at least 40” per turn.  Roll damage inflicted separately for each object involved (rather than once for both objects), and apply all applicable defenses as normal.  This does not require a special roll to hit, provided both of the targets are approximately the same size.  The GM may apply a bonus (or subtraction) of + (or -) 5-10 for a smaller object attempting to run into a significantly larger one, or vice versa.  Additionally, a large object might require a special hit to strike a much smaller target, and a smaller object might not require a special hit to strike a specific area on a very large target.
