Stikkbomb Chukka
From Warhammer 40k - Lexicanum
The Stikkbomb Chukka is an Ork upgrade designed to allow Orks wearing Mega Armour a better chance when assaulting enemies behind cover, although it does mean that they are preoccupied with throwing the Stikkbomb and cannot attack with so much force.
It is also an Ork vehicle upgrade which allows the vehicle to attack enemy forces directly, including vehicles and Ork Dreadnoughts. It also has the effect to demoralise enemy troops.
