Who can field it

  • Grand Cathay · The Northern Provinces

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.

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.
