[Ork warlord 'Waazzza']

well i did play tau so...

Q1) can a battlesuit have 3 weapons & a 4+ invulnerable save? or does the shield generator use-up a hard point?

A1 the shield generator is a 'hard point' and thus 2 guns 1 shield generator
( unless you use a shield drone )

Q2) is there any way to give a tau commander a both a 2+ armour save and a 3+ invulnerable save? (i know iridium armour gives the 2+ save, but can't find out where the invulnerable comes from...)

A2 3+ invulnerable save is a NO unless you use a shield drone or a shield generator which gives you a good invulnerable save but not as good..

Q3) does losing shield drones to shooting count for determining if a battlesuit unit has to take a moral test for taking 25% casulties? (my opponent used 3 single suits each w/1 shield drone)

A3 ....Yes you do have to as it does count as losing 25% casulties
