The following question is just being discussed in a DT forum in Germany, and I'd really like to get your input:

Grenadier X has joined the Axis Zombies. They want to move and attack while using X's Assault. I supposed they could move 3 squares before attacking because their MV of 1 is doubled to 2 and they may move an extra square because of Fast. Others disagree and state that they may move 4 squares, the logic being MV 1 + 1 because of Fast is 2, 2 times 2 because of Assault is 4. I don't think that's right because Assault states that the Movement value is doubled and the Zombies have MV 1, but I admit I'm unsure. What do you say?

You are correct. Assault doubles the Move statistic, in this case to 2. So if you move for one action the zombies can move 2 plus fast = 3 squares. They then use their second actions to Attack.

Great! Thanks for that quick answer!

Agreed, no doubts there.
