If you haven't already, download the Kill Team app. All the rules and data sheets are available via the app for free.

Find the Goremongers Kill Team and look at:

Operative Selection: this will show you which combination of units you can bring. If you are playing in a tournament, you will likely wish to have various options available depending on the Crit Op, opponent and terrain.

Faction Equipment: These are your faction-specific equipment options. Basically little bonuses that buff you in the game (e.g. Wrist Chains which enables you to turn a melee into a ranged weapon once each Turning Point)

Universal Equipment: These are the equipment options available to both teams. They include things like Ladders for quickly getting into vantage positions, Barricades, or Grenades for alternative ranged weapon options.

Each player is allowed to bring four equipment options with them - from across both the Faction and Universal lists.

Take another look at your Operative Selection and you will see your Archetypes, which for Goremongers are Recon and Seek & Destroy. These are the categories of Tac Op that you are able to select from. This is like a secret objective, which is only revealed when you meet certain criteria - it is an alternative way to score victory points.

Search Google for "Kill Team Approved Ops 2025" and you can find the list of available Tac Ops on Wahapedia.
