Advanced Training (3.5e Feat)
From D&D Wiki
Advanced Training [General, Fighter]
You train with the tools of war to an unusual degree.
Benefit: When you are wielding any weapon larger than a light weapon, attacking you with a light weapon provokes an attack of opportunity. This applies to unarmed strikes, even if your opponent has the Improved Unarmed Strike feat.
Normal: Attacking with a light weapon does not provoke an attack of opportunity, and unarmed strikes only do so when the attacker does not have the Improved Unarmed Strike feat.
