The Power of the WAAAGH! When an Ork mob charges into close combat roll a 2D6. If the score is equal to or under the number of Orks in the mob they charge in with a rousing "Waaaaaaaaagh!". All the Orks in the mob double thier Initiative characteristic for the remainder of the assault phase. In future phases their Initiative returns to normal.
Orks who make sweeping advanced into the enemy also tests for The Power of the WAAAGH!. The test is made at the beginning of the assault phase so any casualties from enemy first will reduce the chances of them maintaining their momentum.
Mount Up! All infantry in a Speed Freeks force must be deployed at the start of the battle aboard a trukk, battlewagon or looted vehicle. During a game, any mob of Speed Freek Orks is allowed to mount up onto any transport vehicle they can fit onboard; they are not restricted to only using the transport they were deployed in at the start of the game.
