The Rokkit Rangerz are a small Ork klan that formed a part of Warlord Gorgutz's WAAAGH!. It is common for Ork klanz to become part of other Ork tribes if their Warboss is killed by another Ork leader. Warlord Gorgutz used this method to quickly build a massive Ork invasion on three separate occasions; first on Lorn V, then Kronus and finally a massive assault was launched by these Greenskins upon the Kaurava System. Most other large scale Ork invasions (like the wars for Armageddon) have been formed in this way. One klan must simply destroy another klan's leader, and the most likely outcome is that the klans will merge and eventually form a WAAAGH!.
