At 7th level, an unarmed fighter takes no penalties to Dexterity or on attack rolls while grappled, and retains his Dexterity bonus to AC while pinning an opponent. The unarmed fighter can make attacks of opportunity even when grappled and even against creatures attempting to grapple him if the opponent has the Improved Grapple feat or the grab ability. This ability replaces armor training 2.
