Centurion V, here we go. The hard kill APS system can now take out threats from the top and spin 360°. The Hull is different, being more suitable for battle and with a lot more cage armour. There are now ER blocks over the usual AAPSERA armour. More smoke launchers. There are enough cameras to obtain a 360° degree view of the area around the tank. A new 140mm smoothbore cannon. Better software. An optional automatic targeting system. Updated Tracks. A new optic sight. More lights. More armour at weak points. Better APS system (Ultraviolet sensors)
Should be able to withstand a lot of damage. @krinkus, who literally remixed the Centurion IV and made these amazing tracks as an upgrade New Anthem, Aka the Astanislavian Anthem. This isn't even an update anymore, it's literally a tank development war between SC and Umbra.
