Taurian Concordat: To represent the large number of rocket launchers on periphery designs, a Taurian player may designate any unit to cause an extra click of damage per 100 points the attacking unit is worth (rounding up) once per game. So for example, a 250-point unit does three extra damage, a 25 point unit does one point extra, and a 99 point unit still only does one extra. This also costs -1 to the attacker's to-hit number, and causes one extra click of heat whether the attack hits or not.
...this rule is moot if the defender is a House Davion/Swordsworn army, in which case the Taurian player is required to get under the nearest table, refuse to come out, and mutter "they're all out to get me" (or something similar) while sucking his thumb.
