Who can field it
- Greenskins · Grimgor's 'Ardboyz · extended roster
Custom Battle lists factions under each race; every faction of a race fields that race's units (units_custom_battle_permissions rows of any of its factions). The name after the race is the faction the army builder uses.
Extended roster: every race above has this unit only through campaign_exclusive rows of units_custom_battle_permissions — CA's note: such units are “filtered out of matchmaking and are generally disabled when unit caps setting is enabled” (“Unable to recruit with unit caps enabled”). So: Custom Battle with Unit caps off, at the multiplayer cost, but not in ranked battles. Race rankings and best-unit lists leave such a unit out for those races.
Where these numbers come from
Read from the game's database tables for patch 9.0.4 (main_units, land_units, battle_entities, melee_weapons, projectiles…) as published in the WH3-Dump export (commit 099796e8). Formulas that turn table values into card values are checked against known units before they are shown — how we verify.
