Hmm, ok there are some things, that could work, but:
What do you do, if the Mishima only wait behind the building walls for your attack?
How would you dig them out? For this there were the Sunsets with their two flamers.
Because of that I think this scenario ist unfair for the attacker. He needs more points.
When you can leave the Sunsets two Squad Rangers could work, or maybe two Squads of
Wailing Banshees, they have better Armor and are fast at the front.
The Airborne were useless, I learned that. It is to difficult to land them properly on our field.
To get closer to the Snipers was the problem. There was this 20'' killing zone we couln't pass
and the distance to the Snipers was over 24''.
You talk so easily about taking down a battlewalker. Maybe with luck you can do this with a squad, but it is very hard
and then your Squad is wiped out after that, by the three remaining battlewalkers and the snipers.
And I forgot, what if the Mishima Battlewalker use the "vehicle pop out and hide" tactic?
Yes I missed my Colonel, but I had no points left for him.
But thanks for the advices. Maybe I try to field a second Great Grey and this time pass some saves.
