The rich and powerful take what they want. We steal it back for you.
3+ NVA troops cannot bombard adjacent spaces - unless adjacent space is attack destination. Correct?
Nope. NVA's Bombard priority states:
Select Attack or March destination spaces first, then other spaces with NVA pieces in them, then where US Troops, then randomly.
If they can't Bombard anything they're Attacking or a space that has NVA pieces (any NVA pieces, they don't necessarily have to be a group of 3+ Troops), then they'll go after any legal space, choosing those that have US Troops to remove first.
