Do 6's still auto wound against warmachines? The shooting at warmachines rules say that you use the machine toughness, but are firing at the crew, representing them hiding underneath it. I had a game where I tried out using scouting chameleons to take out a gunline, but was met with my opponent saying that the poison doesn't autowound because it is hitting the machine, and you would need high strength to smash through it.
Yes, 6s auto wound! Your opponent needs to re-read his rules. Yes, his crew is hiding behind the machine, the 6s represent the poison hitting his crew (as they are wound markers now).
Arli is correct! This is the reason why chamo skinks are such an amazing unit under the 8th edition rules!! So happy warmachine hunting to our little camouflaged friends!
