This looks more functional than additional ammo storage of 90M (which is never being used from that I heard)
Edit: Interesting. Pic 2 indicate 4 as “Removable compartment with additional auto-loader”, while pic 3 shows different autoloading mechanism (similar to 292 in game, with rounds stored in hull and chargers in turret)
At that point just add T-90m with arena-m, t72b3 with arena-e, t-72m1m with arena, t-80um1 with arena, bmp-3 with arena and t-62m with t2a2 (drozd) aps
I have a feeling we will see them sooner than later. 14.0 smells like a fertile ground for the “next gen” (in relation to existing) missiles. Especially for nation which dont get better Fox-3 without just going completely overboard in their capabilities
