Re:Armor

The current FT "armor" seems to me to simulate Traveler
sandcasters--omnidirectional, one box protects the same whether for a DD
or
SDN, and it's ablative.

How about "real" armor?  For example, 1% of hull mass for each face
protected, stops 1 point of damage from every weapon, not subject to
threshold checks and doesn't reduce rerolls.
