[In-game spotting system: are you kidding me?]

Another test 
Same map & conditions, abrams spotting abrams. test is run 20 times.
On average:
? 40 seconds
Identification 46,35 seconds

and M1152 Humvee spotting abrams, (two man crew, binoculars available) this test is also run 20 times.
On average:
? 20,75 seconds
Identification 43,3 seconds

At least trucks need some further inspection... Abrams seems to be ok.

[In-game spotting system: are you kidding me?]

yeah, 8 runs is a bit small sample, but is it even possible to see tank 3km away with naked eye? 

 Scenario file attached.

Quick spottin test:
T-90AM, T-72B3, BMP-3M, BMP-2M, BMP-2, BRM-3K and Ural are trying to spot single abrams (empty) 3000 meters away. Regular, +0. Vehicles have been separated by tall wall and  electronic warfare is set to: strong (to prevent them from communicating). Map is flat and  weather is clear. Test is run 8 times. 

Test results:

On average
T-90AM spot ? after 53s and got positive id at 1min 4s
T-72B3 spot ? after 1min 23s and got positive id at 1min 34s
BMP-3M spot ? after 44s and got positive id at 1min 5s
BMP-2M spot ? after 2min and got positive id at 2min 17s
BMP-2 spot ? after 1min 54s and got positive id at 2min 8s
BRM3K spot ? after 2min 1s and got positive id at 2min 24s (longest spotting time, though ew might have some effect on radar. "dismounts" are also missing)
Ural spot ? after 24s and got positive id at 39s! ( Uaz and at least some humvees have also insane spotting times)



 

[Armor Protection Data for T-90 series seems to be underestimated]

I did some testing:

 

AT-7 vs T-90AM front hull:

Penetrations: 6

Partial penetrations: 21

Non-penetrating hits: 25

 

AT-7 vs T-90A front hull:

Penetrations: 6

Partial penetrations: 17

Non-penetrating hits: 27

 

AT-7 vs T-72B3 front hull:

Penetrations: 16

Partial penetrations: 24

Non-penetrating hits: 8

 

Tested also MT-12 vs T-90AM @ 300m, most of the hits were either partial penetrations or armor spalling. few shots achived full penetrations against front turret / upper front hull (using APFSDS)
