rule.
But in some cases layers of armor should have some effect. I've heard
comments that two layers of, say, kevlar isn't better than one,
simply because if the bullet can go through one, it can also go
through the other, or some such. I have no idea if this is fact, but
it is an ok 'basic assumption' for my purposes.
SR armor values is based on the 'overall' protectiveness of the
garment. So an armor jacket, which covers only the arms, torso(f,b),
is significantly sturdier than a trenchcoat, which covers the entire
body sans head.
Using the cybertechnology division of armor locations, we have head,
torso front, torso back, arms, legs. Five locations. An armor jacket,
with 5/3, therefore has an individual armor value for each location
of (5*5)*3^-1/(3*5)*3^-1 = 8.33/5. A trenchcoat has 4/2, but covers
each location except the head, giving it 4*5/4 ballistic and 2*5/4
impact, for 5/2.5.
The idea is, add all highest armor value of each location
together, and divide by five. Normal rounding off rules.
That is the effect of the armor worn.
So, wearing an armor jacket and trenchcoat, for instance, looks as
follows:
H: -
Torso, f 8.33/5
Torso, b 8.33/5
Arms 8.33/5
Legs 5/2.5
Total 30/17.5 = 6/4
The special armor types - helmet and combat boots - has 5/5 armor
value. Wearing more than two layers of armor in a single location
may becomes uncomfortable, giving heavy armor penalties.
Revised armor values of BBB armors:
Name Protected locations value
Armor clothing T(F), T(B), A,L 3.75/0
Armor Jacket T(F),T(B),A 8.33/5
Armor vest T(F),T(B) 5/2.5
-/- with plates T(F),T(B) 10/7.5
Lined coat T(F),T(B),A,L 5/2.5
Helmet H 5/5
Any combinations of the above is then easy to figure out.
(I did all calculations in my head. They might be off. The formula
for the values is (Original armor value*5)/number of locations
covered.).

The undiscovered country, from whose bourn
No traveller returns, puzzles the will,
And makes us rather bear those ills we have,
Than fly to others that we no not of."
