For an Ork Vehicle it lacks lots of Dakka and even more Dakka.
But ye… you asked for a Profile for this… nevermind…^^
Gretchin Storma Bike
Suicida Kanon | Heavy | 100m | S/-/- | 4D10+5 I | 4 | 1 | 2Full | Inaccurate, Unreliable, Blast 3, Overheating, Special
If driven by an Ork or Gretchin the Weapon losses its Unreliable Trait and if it is fired by an Ork or Gretchin while braced it losses the Inaccurate Trait too.
If an Overheating result appears the whole Bike is destroyed and its pilot recieves 4D10+5 Impact Damage with a Penetration Value of 4. Additional he recieves 1D10+3 Impac Damage because of the drop from the bike when it was accelerated during the Overheating.
The Gretchin Storma Bike was first spoted used by the "Elite Storma Squadron" led by the Gretchin reported as "Kaboom" whose so called Suicida Kanon overheated and ingnited the Fuel of his own Storma Bike. The rest of his Squadron attack an imperial breachhead during the actions of the thrid war of Armageddon where the recoil of the mounted weapon decimated around 75% of the storma suqadron without any imperial involvement. In the End of the Fight atleast three of the estimated fifteen fired rounds were confirmed hits at the imperial fortification, destroying the Latrine of the defending Guardsmen.
