Combat Maneuvers

This house rule ensures that characters untrained in combat behave as such. It elaborates on an optional rule for "Untrained Fighters" given in GURPS Martial Arts 4th edition p. 113. To that end, some combat maneuvers now have a combat skill prerequisite. Note that it is only necessary to have a single combat skill at the requisite level to use a maneuver--melee or unarmed for melee combat maneuvers, ranged weapon for ranged combat maneuvers. E.g. if you have Brawling at DX level, then you can use all of the melee combat maneuvers that require DX skill level, even if you're using a sword at default and your sword skill is only 5. An exception is for PCs that have zero points in melee or ranged combat skills: they must have the requisite skill level in whatever skill they're attempting to use (at default) at the time. See the table below (which is a modification of the Quick Reference Table of Combat).

Having at least one melee/unarmed and one ranged weapon skill at DX level means you have access to all possible combat maneuvers, making this house rule moot for such a character.

Attack Options

These effects may be combined if the maneuver allows them, except for Rapid Strike and Dual-Weapon Attack are mutually exclusive. Weapon Masters and Trained by a Master halves the penalty for Rapid Strike and Dual-Weapon Attack.

Attack Options	Effect	Skill Level

Extra Attack	Take an extra attack. You must have a specific advantage to do this.	n/a

Active Defenses

Normally, only 1 Active Defense can be attempted against a single attack. Some maneuvers prevent a defender from using certain Active Defenses. All Active Defense are at a -4 penalty while Stunned. Multiple uses of the same Active Defense in a turn accumulate penalties that are zeroed at the start of character's turn.

Weapon Masters and Trained by a Master halve multiple parry/block penalties. Fencing weapons, long two-handed weapons, or mobile unarmed skills (Boxing, Karate, or Judo) also halve multiple parry penalties. Effects are cumulative (-1 penalty for multiple parries).

Active Defenses	Effect	Skill Level
Parry	One per arm. Can only cancel melee attacks or thrown weapons. Additional parries are -4 per arm repeated.	DX-6
Cross parry	Requires a weapon in each hand, and can not make any further Active Defenses with those limbs. Make a parry at +2	DX-5
Supported parry	Support a weapon parry with an empty hand. Cannot make any further Active Defenses with those limbs. Make a parry at +1	DX-5
Block	One per arm with a shield. Can cancel any attack. Additional blocks are at -5 each.	DX-6
Dodge	Can cancel any attack. No penalties for additional dodges.	DX-6
Acrobatic Dodge	Can cancel any attack. Only one attempt per turn. Roll Acrobatics; success gives Dodge +2 and failure gives Dodge -2.	DX-6

Retreat Options

No character can retreat more than once per turn. Some maneuvers or postures do not allow retreats. It is never legal to retreat into obstructed terrain.

Dive or Drop	Go prone in current space	+3 to Dodge against ranged attacks or +2 to Dodge, Fencing Parry, or Mobile Unarmed Parry against melee attacks or +0 to Block or Parry against melee attacks	DX-6

Low Line Parry	No movement	Counts a parry for maneuvers that limit parries and requires at least 2 functional legs. Roll a parry against an attack below the waist.	DX-5

Grappling

Grapples are initiated by any attack maneuver at Close Combat range. Any Active Defense will cancel a Grapple attempt. The following actions are attack options after a Grapple has been started.

Action	Effect	Skill Level
Break Free	After being grappled, initiate a Quick Contest of ST. On a win, the grapple ends and you may Step in any direction.	n/a

Judo Throw	After a Judo parry or a grapple, attack with Judo. If successful, opponent is prone and must roll HT or be stunned. Roll at -1 to do thrust/crushing damage to victim. If the opponent is in a lock, do swing/crushing damage to the body part in the lock.	DX-2

Neck Snap or Wrench Limb	After grappling a foe's limb or neck, initiate a Quick Contest of ST-4 versus ST or HT. If you win, do swing/crushing damage to the limb or neck.	n/a
