From D&D Wiki
You are trained in infiltration.
Replaces: If you select this class feature, you do not gain a fighter bonus feat at first level.
Benefit: Add Hide, Listen, and Move Silently to the fighter class skill list. Gain one rank in each of these skills. Each second fighter level beyond first, you gain one additional rank to be placed in one of these. You may place your normally gained ranks in these skills each level if you'd like.
