Unit 11: T-54B
1) Weapon n. 54 12.7 DShK AAMG should be replaced with weapon 4714.5 ZPU-1 AAMG
Replacement of the 12.7mm AAMG with the 14.5mm AAMG seems to be a standard feature for North Korean AFVs
2) Loadout could be changed to 15 HE 13 AP 6 HEAT
Unit 12: T-55A
FC should be increased to 7 (see unit 10 T-55A in Russian OOB)
Unit 14: T-62
1) Weapon n. 54 12.7 DShK AAMG should be added in slot 3
2) Availability date changed to 1/1970-12/1994
This would be used to represent the imported and non modified T-62

Unit 15: T-62M
1) Weapon n. 54 12.7 DShK AAMG should be replaced with weapon 47 14.5 ZPU-1 AAMG
2) Loadout could change to 20 HE 10 Sabot 10 HEAT (standard T-62 loadout)
3) Name should be changed to Ch'onma-Ho
This would represent both early production Ch'onma-Ho and refitted imported T-62s. Replacement of the 12.7mm AAMG with the 14.5mm AAMG seems to be a standard feature for North Korean AFVs.
Unit 16: T-62M1
1) Initial availability date changed to 1/1985
2) Name change to Ch'onma-Ho II
3) Weapon n. 54 12.7 DShK AAMG should be replaced with weapon 47 14.5 ZPU-1 AAMG
4) Loadout change to 20 HE 10 Sabot 10 HEAT (standard T-62 loadout)

Unit 583: Ch'onma-Ho IV
1) Initial availability dates changed to 1/1990
2) Weapon n. 54 12.7 DShK AAMG should be replaced with weapon 47 14.5mm ZPU-1 AAMG
3) Loadout change to 20 HE 10 Sabot 10 HEAT (standard T-62 loadout)
As it can be observed from the pictures posted the tank is equipped with a 14.5mm AAMG. It was shown during a parade in 1992so 1/1990 seems a good guess for initial date.
Unit 17: T-62MK
It should be deleted, such version was never in service as far it is known .
Unit 19: Type 59
Availability date changed to 1/1973-12/2020
HE load could be increased to the expense of AP rounds as that would be more in line with known combat loads.
Unit 20: Type 59-I
It should be replaced with a clone of unit 19 Type 59 with the following changes:
1) Availability dates 1/1985-12/2020
2) Weapon n. 230 12.7mm 54T AAMG replaced by weapon 47 14.5 ZPU-1AAMG
Replacement of the 12.7mm AAMG with the 14.5mm AAMG seems to be a standard feature for North Korean AFVs.

Unit 34 BRDM-2 Susang
VIRSS should be deleted (no such countermeasure is reported to be in service)
Initial availability date should be changed to 1/1991
Weapon n. 155: Susang Po ATGM
HEAT penetration should be increased to 46 at least.
Currently it has a lower penetration than weapon n. 146 9M14 Malutka (40 vs 46). According to SIPRI North Korea has manufactured Sagger ATGMs under license and this Susang Po is described by nearly all sources as Sagger variant, presumably one of the later ones with SACLOS guidance, which is also consistent with the greater accuracy rating in the game (70 vs 60). Warhead penetration should not be inferior to that of an early variant.
