I have realized that for war Threads to proggress a little more smoothly we must iron out our individual weapons and defense systems and how they work in regard to one another. this thread is meant for discussion and deciding how these things are handled.
first off
Durium Armor: durium is the metal used by the Coalition nations as their standard from of ship portection. Durium acts like a sponge for direct forms of energy(EM waves, radiation) and it cools that energy down so that it doesnt cause any problems. this makes Durium well suited towards taking on Laser weapons, nukes, blaster weapons and such. however heat affects Durium differently and it must be sheaded off naturally which means heat based things like plasma work much better than lasers or blasters. kinetic weapons simply shear durium into peices though. Durium is a flexible yet heavy metal so it warps and twist it self out of shape unless it is supported or not packed all together.
Durium either comes in two forms, a chainmail style that simply soaks up a burst of energy then flakes off or in large sheets braced by a denser harder metal.
on modern ships a grid of wires and pipes work to take excess energy that would normally overwhelm the metal and send it to radiators to be radiated off. this grid is sandwhiched between the durium sheet and the Tungsten sheet.
durium can be overwhelmed by direct energy weapons when they are fired all at the same time in focused amounts or in a concentraion. Durium can be melted down by heat based attacks(plasma) and heat based attacks are better when they are focused on a single point. and durium is not the hardess metal around so kinetic based attacks do a great job of tearing right though the armor.
a railgun round which is the primary weapon on alidina ships fires rounds at extremely high velocities, in most cases this speed is enough so that it can pass though a shield and hit the armor(or hull if there is no armor). it does this because shields take time even a single milisecond to effect the round but in that milisecond the round is already mostly though the shield and still cruising along so unless your shields work a different way from the normal deflector shields then most of the time railguns will pass though your shield
fixed
but I can see that so 
I sorry toishima im having... Technicaly difficults and cant post at the moment)
