As I understand it, no. As jetbikes are treated as infantry, they are unable to screen anything with an armor value.
What if i get a squad of jetbikes, and then get that eldar character who rides a vyper within 6 inches?, what then? i mean if you can hurt a vyper you can easily hurt a jetbike.Originally posted by ArchonAstaroth@Apr 28 2003, 05:37
Yup, only terrain and vehicles can block LOS to another vehicle.
However, that being within 6" of another viable target is an additional rule and it works only for independant characters. A vyper isn't an IC, so this rule cannot protect it either. Also note that "viable" means that at least one weapon of the shooting squad has to be able to damage that alternative target. You cannot protect a chaplain by moving a land raider next to him if the opponent has no weapons which can harm the land raider in that squad which he wants to use in order to kill the chaplain. You could block LOS with that land raider though.
