Welcome to Librarium Online!
Got a question on the destroyers:
In the codex they move as Jetbikes, but it says they can fire after movement.
Does this mean they can use the "Turbo Boost" to fly at flat-out speed and THEN fire their Gauss cannons?
Jet bikes don't go Flat Out, Skimmers go flat out
how ever i don't have an answer but i would say no because the idea behind can't shoot after turbo boosting is that your going to fast to hit, the rule was meant for moving and firing a heavy weapon
The only one that I know of that can do both (turbo and fire) is one of the Ork special characters on a bike. Wazdakka or something like that
if your relentless you can if i remember correctly
if you're relentless i doubt you'll be turbo boosting...
Relentless (pg 76) allows units to shoot as if they have not moved.
This simply allows them to move normally. A unit that turbo-boosts forfeits its shooting, among other things (76).
