Omaha Scenerio Turn 1 Air interdiction US Side

[HercMighty]

When I hit the up arrow the playable area turns purple and I cannot place a marker anywhere. Okay I look at page 14 of the manual section 8 and it says nothing about color of hexes and I cannot get the purple color to go away. Anyone know what I maybe doing wrong or where the purple color is coming from and why I cannot get it to go away?

I still also do not understand why I cannot place air interdiction either.

The purple zone shows the NO PLACEMENT zone for air interdiction. You have to land a unit first. Once you do that you'll be able to place air interdiction (out to 15 hexes from your units).

Purple overlay is telling you need to invade the continent in this scenario[X(]... once you've invaded the purple will go away when you place your air interdiction down to protect the invading troops[:D].

Okay thanks. Things are starting to make sense. I did figure out how to unload troops and it did as you said. Thanks
