In the real world protective armor, like the Armor Belt SM: P VM p. 99, is replaced by newer armor, gets damaged in combat or by crashing into something, say a mountain side.
I've checked my books and the DataNet PDFs without finding away to simulate patching the damaged armor belt.
Here is my idea for simulating armor replacement:
Enter the amount of armor needing to be replaced up to the original amount.
Enter the Armor Belt Protection DB if different from the original purchase.
Select the CAT of the Armor Belt if different from the original material installed.
Replacement Armor Belt Mass = Mass installed
Replacement Armor Belt Cost = (CAT Cost Multiplier x Replacement Armor Belt Mass x Armor Pelt Protection Cost Multiplier)
Example: A TL 25 TMAC, the Tanya named for the pilots girl, with CAT XVI with a +5 DB has lost 2 tons of Armor Belt in combat. Due to the intensity of combat resupply of parts and material is hit or miss. In this case the last of the CAT XVI replacement armor in supply and anything scavenged from other craft have been used. There is a supply of Reinforced Crystanium CAT XV that the Tanya's crew chief can get through supply. Cutting a new supply chit, the CAT XV armor cost is:
7 (CAT XV Cost Multiplier) x 2 (CAT XV mass used) x 100 (DB Cost Multiplier) = ¢1,400. With some sweat, and a lot of cursing by the ground crew, the Tanya is made ready for the next sortie.
Does the above idea work and sound reasonable or am I out to lunch?
