If a Warboss is your Army General, then once per game he may call a Waaagh! The Waaagh! may only be called if the Warboss first declares a charge, and must be announced immediately after making the charge declaration, before any charge reactions take place. In the turn a Waaagh! Is called, every unit of five or more Orc Boyz, Savage Orc Boyz, Black Orcs, Boar Boyz and Savage Orc Boar Boyz in the army (including Big 'Uns) adds +1 to its combat resolution for the rest of the player turn. The General himself, and any unit he accompanies, adds +D3 to their combat resolution instead.
