Warhammer 40K Combat Simulator

Welcome! This tool simulates Warhammer 40K 10th Edition shooting phase combat. Here's how to use it:

1. Use the Form Input section to define your attacking (Shooting) and defending (Target) units.
2. For Shooting units, each unit has a Name/Qty and can have multiple weapon profiles. Keywords can be applied at the Unit level or Weapon level.
3. For BS, Invulnerable Save (Inv), and Feel No Pain (FNP), you can enter 'NA' if a unit does not have that statistic.
4. Click Run Simulation and view the results below.

Unit Keywords:

• ReRollFailedWounds: Re-roll all failed wound rolls for all weapons on this unit.
• ReRollWoundsOf1: Re-roll wound rolls of 1 for all weapons on this unit.
• ReRollHitsOf1: Re-roll hit rolls of 1 for all weapons on this unit.
• ImproveBS1: Improves the Ballistic Skill (BS) by 1 for all weapons on this unit (e.g., BS 3+ becomes 2+).
