They need artillery otherwise they die horribly.

Corvus will sneak attack since no avengers are there to keep him busy

I think they can do it.

Cull fought the Hulkbuster, no one is downing him.

They just need to last 8 minutes? They can probably do it.

@alavanka: yes more or less

If the National Guard gets attack helicopters they win.
