Vehicle Squadrons

If you run vehicles in squadrons (in my case buggies or kans) what happens when one or two vehicles are immobilized? Can the third vehicle desert them and soldier on, or does it have to maintain unit coherency with the immobilized or stunned teammate?

Stunned or Imobilized, in a squadron, count as destroyed.

dont have a rulebook handy, but dont vehicle squadrons count stunned as shaken?

pg. 64, 2nd column...1/2 way down. If "Imobilized" counts as wrecked, if "stunned" counts as shaken. So you either kill them or they keep moving, all be it the stunned one can't shoot.

So what are the benefits of squadrons? Just enable you to get more vehicles into one fast attack slot?

Well what's better than one Killa kan? 9 killa kans! They are usually dirt cheap, and you can take crap-loads of them. You can get 9 walkers for heavy support, and 9 buggies for fast attack. Add in a big mek for Kustom force field and the fact that you can space them out 4" instead of 2". And you get happy fun time.

I've been playing a couple in my 750 games at Yotta, and they are great. I have a couple store-bought and have scratch built some more...

So wait, do you still have the option of destroying it? or it automatic now?

It's auto

Bear in mind that since Stunned goes to Shaken automatically, you only need to buy Extra Armor for 1 model at best (and try to make that model the last one, when it will get stunned and immobilized normally)
