Subject: Armour
I have been following the armour thread on ships armour and had some ideas and observations. There seem to be two aspects of armour that people are trying to model for FT/MT. The first aspect which the Kra'Vak armour represents very well is rigidity. You can either damage the ship after penetrating the armour or you scratch the paint and nothing else. No in between. This models Tank armour pretty well I think. If you can punch a whole in an M1 then you can really screw it up. Punching a whole is very difficult. The other aspect of armour that is being discussed is ablative armour. You hit something and damage it but it has plenty of stuffing so that it can withstand that easily. Runways are often designed to be compressed dirt with steel reinforced concrete on top and finally layered with armour plate. I may be wrong but I think that describes the runway at Ke San in Vietnam fairly well. It survived heavy bombardment and was relatively easily fixed after each assault. These systems don't shrug off a shot without noticeable change; a shell striking a concrete/steel/dirt runway will leave a crater. It will probably not penetrate though. Similarly this is a quality shown by ships by having increased compartmentalization, armoured internal bulkheads and improved damage control/fire fighting equipment. An american cruiser in our modern navy may survive a strike by an anti-ship missile, but there will be a whole in the ship. The present 1 mass cost 2 per point added to DP, to the ship armour seems to be a good representation of this. (there was an incident during the Iran-Iraq war where an american ship suffered an Exocet missile hit and survived, with a significant loss in fighting ability and several lives) All that said I think we should have both systems. With a small change to the Kra'Vak armour. Rigid armour when penetrated tends to loose structural integrity. I think a good way to represent this is to simply add a system that sustains threshold rolls to the Kra'vak ships that represents the strength of the armour. One system for each level of armour.
