This was originally going to be the second half of my post on 6th Ed Transports, but I didn't want to hijack the thread. Thus...
My pet peeve with transports has always been, I blow up the transport, kill the crew deader than Elvis, leave a crater for God's sake, hit everything within x inches... and yet there's the passengers, in the middle of a blast that just turned the toughness 14 hull they were inside of into shrapnel, saving against the hit. Where, pray, did they find cover? Maybe under the crew? Maybe there was a layer of plastic explosive incorporated into the vehicle so that in the event of catastrophic damage the blast directs 95% outwards?
My version: vehicle wrecked, follow current procedure - the passengers are banged up by the impact. Vehicle destroyed, every model inside takes a wound, no save.
