# Invisibly forces certain units to always have a specific chance to hit
# when fighting against certain other units.
#
# Note that the player still only sees the regular damage calculations, so
# this is useful if you need to give an invisible helping hand to the player
# or AI. For example, if the player is forced to attack with only a couple
# of units at the beginning of a scenario, you can use this to ensure that
# simply having bad luck cannot ruin their attempt so easily. Also you might
# have enemy leaders which the player is not supposed to fight or be able to
# defeat due to storyline reasons, but could theoretically still kill with
# some clever trick, AI mistake or sheer exceptional luck.
#
# An example which forces Konrad's attacks to always hit Li'sar, but only
# after turn 10:
#! {FORCE_CHANCE_TO_HIT id=Konrad id="Li'sar" 100 (
