In the Secured Area battle builder condition, each side gets 50 AP of fortifications to place, limited to Minefields, Dug-In, and Camouflage. However, there is nothing about where these can and cannot be placed. Is there any official ruling on how this is supposed to work?
It can make a huge difference. If limited to your deployment zone, they can be worthless and/or overcosted depending on the objective/situation ("Men, we mined our own position"). If unrestricted, you can drop a Dug-In unit or 5 into your opponent's deployment zone (surprise!). Some official guidance would be greatly appreciated and this might be a great candidate for a future FAQ/errata.
