What set of features would you choose to defend your tank on the modern battlefield?
ADT-140 set that comes with a 30mm programmable ammo turret (150 rounds) + backup 7.62mm (200 rounds) both auto aim, Diamant/PROMETEUS APS (I counted 24 slabs, 2 rear-facing, 4 forward-facing and 9 on each side, 2 charges per slab look-up and look-down), ECLIPSE RF jammer and GNSS spoofing, common ERA+NERA, Galix 13 80mm smokes (thicker and longer lasting)
OR
KF-51U with a 7.62 auto aim turret (2500 rounds), Iron Fist aps (between 4 or 6 rounds apparently, 2 or 3 in each side), strikeshield aps/ERA all around, MUSS 2.0 IR and rf jammer + GNSS spoofing, 4 HERO-120 drones (technically it's an offensive thing but it should be no problem to employ it in a defensive manner), ROSY 40mm smokes (not as thick, doesn't last as much but deployment is sub 1 sec vs 1,5 sec of the Galix)
