Arena-M is probably the most efficient APS because of its 40 ms reaction time compared to 300 ms on the iron fist and Trophy.
Which means it can defend against close fired threats better than anything else?
What’s the minimum distance that it can detect and defend against?
It has a reaction time of less than a second at .03 so I would assume so.
3bm59 is as much in serbice as the t14, they barely use 3bm60 which is their supposed main round (3bm42 is still extremely common ly used by russian tanks) let alone 3bm59. But yeah it could be a good addition
Challenger 3 is not that major of a vehicle. Its essentially an hodgepodge of most cr2 upgrade packages over the years. Its not even a good tank ingame
