Modern Combat

See also: Vehicles, Surprise and Tactics.

The main complication for modern combat is automatic fire. These are some brain storming notes for the main set of rules which can be found at

New Firearms Rules

See official rules for current set of rules. These are some ideas for updates based on player feedback.

Current possible issues:

  • Triple shot is worse than multiple shots for some weapons.
  • No penalty for multiple shots with lasers.

Multiple Shots

When using the multiple shot manouevre:

  • The base fumble chance is equal to the number of shots.
  • The recoil penalty applies to subsequent shots.
  • -5 penalty to all shots per number of shots over your skill.
  • -10 penalty per target beyond the first, if have Multiple targets technique.

Three round burst

Special form of automatic fire, only possible if the weapon is designed for it.

  • Burst is a single attack. If it causes damage, doubles the wounds/stuns caused.
  • A gun has a hardware limitation of a number of bursts equal to the number of fully automatic bursts it can fire (i.e. 1 three round burst per 10 RoF).
  • You may fire multiple bursts, each subsequent one suffers recoil penalty and the base fumble chance is twice the number of bursts.

Triple shot technique

  • Three rounds, all one attack. Any damage caused is tripled.
  • Only once per round.
  • No modifier to the fumble chance.

Firearm ranges

Some thoughts about ranged attacks with firearms.

Typical infantryman, with Perception 3 and skill 4 and M1 Garand (+7 Atk, 20m increment).

Type of shot 50% Range
Snapshot 20m
Normal 80m
Careful 160m
Aimed 240m

A similar infantryman who has the 'Sharpshooter' technique.

Type of shot 50% Range
Snapshot 40m
Normal 160m
Careful 300m
Aimed 360m

Now we give the same guy a x2 scope (+5 accuracy) when aiming. This takes the weapon up to the maximum short range of the weapon.

Type of shot 50% range
Aimed 450m

For a springfield with x2 scope:

Type of shot 50% range
Aimed 550m

Someone with Perception 4, Skill 6 plus x2 scope can shoot out to 750m.

A highly skilled sniper, Perception 5, Skill 8, plus x2 scope can shoot out to 1000m.
