Campaign Creations

In the first level that you play, when your marines get disguised as scv's and you need to drop the crystals off at the hospital, how do you get them to do that, they just attack the medics and civilians whenever i try, and I end up running out of time.

I have it set on use map settings.

Thanks for any help.

I believe you either just take them to the destination or a beacon, I don't recall exactly. "drop them off" is just telling you "take them there"
