Size of Fortifications

This was asked and answered in the WhatsApp Impetus group.

Some army lists provide for the purchase of fortifications, typically 5 points per section. I asked what size each section of fortification is, and Lorenzo answered that each section is 2H in length and whatever depth that is the minimum necessary.

Edit - I edited the comment on depth.

Actually, depth is the minimum necessary.

I'm sorry, I misread Lorenzo's post, and corrected my initial post. Fortifications definitely look better at 1h depth or less. Thanks Jorneto.
