1) Do drivers get XP for ramming/running other models over?
No. Drivers have to get their XP in good proper Orkie fashion like all the other Orks. They must shoot or whack other models in hand to hand. Ramming (or hitting with a wrekka ball) will not get the model any XP.
2) Is income generated from ransoms (and other lump sum payments) "taxable?"
Some things are added to 'income' and are therefore subject to deductions for booze, etc. Others are just added straight to your teef hoard. Unless it says it is added to your 'income' there are no deductions.
3) If you roll and hit the Gubbins, and penetrate, only to find there are no gubbinz (so you then go to engine) do you need to roll to penentrate again (against the engines) or just accept the first roll?
This is the procedure:
Roll to hit.
If hit, roll for location. This is the final location (gubbins goes to engines and so
forth). This is the reason we left a blank hit location table on the Buggy Roster, so that
if a vehicle doesn't have a particular location you fill in the alternative location for
that number (i.e. write in Engines instead of Gubbins, withthe appropriate armour
value). Work out penetration and damage.
1) Are units on flak special orders allowed to fire at interceptors as they are placed in position to attack their inteded targets?
No. Since the flyers were not moved across the table, the flak units are not entitled to a shot.
