Retrofit walkthrough: This is a guide explaining what each retrofit means. As a good tanker, you should run your tank once with no retrofits to see what retrofits are the best. These can make or break a tank so look what it needs not what you want.
Armor
Reinforced Wheels: It gives your wheels or treads more HP - This increases track and tire hit points, making it harder to be tracked or wheeled. Mk. 1: +26.67% to tire/track HP Mk. 2: +34.47% to tire/track HP Mk. 3: +40.00% to tire/track HP
Improved Spall Liner: Adds Hit Points to hull, can potentially save your crew - Common misconception here is that it adds hit points to your crew. It doesn't. ISL only gives your crew an increased chance of survival when hit by a shell. Mk. 1: +4.95% to hit points, +15.00% chance to save a crew member Mk. 2: +6.19% to hit points, +18.75% chance to save a crew member Mk. 3: +7.42% to hit points, +22.50% chance to save a crew member
Internal Hull Reinforcement: Adds Hit Points to hull - gives your tank more survivability, does not improve anything else Mk. 1: +7.50% to hit points Mk. 2: +9.38% to hit points Mk. 3: +11.25% to hit points
Reinforced Engine Housing: Adds Hit Points to hull, adds Hit Points to engine - Gives your tank more survivabilty and adds to the durability of your engine, making it harder to damage/destroy your engine. Mk. 1: +4.95% to hit points, +25.00% to engine hit points Mk. 2: +6.19% to hit points, +31.25% to engine hit points Mk. 3: +7.42% to hit points, +38.75% to engine hit points
Reinforced Ammo Rack: Adds Hit Points to hull, adds Hit Points to ammo rack - Gives your tank more survivability and adds to the durability of your ammo rack, making it harder to damage/destroy your ammo rack. Therefore, it also gives a bonus percentage of not being ammo rack killed Mk. 1: +4.95% to hit points, +25.00% to ammo rack hit points Mk. 2: +6.19% to hit points, +31.25% to ammo rack hit points Mk. 3: +7.42% to hit points, +38.75% to ammo rack hit points
Firepower
Chrome Barrel Lining: Adds damage per shot, decreases your reticle bloom - adds to the DPM of your tank and decreases the amount your reticle blooms when coming to a stop. For you to get the bonus damage, however, you need to penetrate your target. Mk. 1: +3.30% to damage per shot, -10% to reticle bloom Mk. 2: +4.13% to damage per shot, -12.50% to reticle bloom Mk. 3: +4.95% to damage per shot, -15.00% to reticle bloom
Experimental Propellant: Adds damage per shot - adds to the DPM of your tank, adds no extra bonuses to vehicle. Mk. 1: +5.00% to damage per shot Mk. 2: +6.25% to damage per shot Mk. 3: +7.50% to damage per shot
Gyroscopic Stabilizer: Decrease reload time, decreases aim time - Allows you to put more shells down range and be more accurate. Mk. 1: -3.96% to reload time, -7.50% to aim time Mk. 2: -4.95% to reload time, -9.38% to aim time Mk. 3: -5.94% to reload time, -11.24% to aim time
Magnetic Actuator: Increases damage per shot, decreases aim time - Adds to the DPM of your tank and decreases cannon aim time Mk. 1: +- Mk. 2: +- Mk. 3: +-
Advanced MRS: Now... when you firing a shell and especially at longer ranges, you will noticed that your round will drop, now with this drop changes the angle of the shell vrs. armor. now at Mrk 3 this retrofit changes this angle to a 3 degree closer to a 90 degree hit. so as a TD who would more likly but at long range this is almost a MUST... If I had to pick a TD that this is a MUST it would be the B1 Centro.
Advanced Shell Material: Decreases reload time, and make you moving accuracy better (is the same as Min accuracy (Largest circle) smaller, which make aim time less as well).
Augmented Breech Lock: Decreases reload time, and makes Min accuracy (Largest circle) smaller, which make aim time less as well.
Advanced Thermo Sleeve: Simply decreases reload time.
Mobility: Please note the word Traverse means the speed of which the item ROTATES, besides that this section is simple and straight forward.
Technology: the only things in here is note Component saves and crew skills is add like i said Improved Spall Liner. Simply i get this much and INCREASE of this % of this %. For Instance Intercom system i get at Mrk 3 7.5%... so if i get 6% faster reload off a crew member I now get 6.45% faster reload.
