Update
Russia:
Minimum nubers of tank "on duty":
~225 T-90A
~130 T-90
~250-270 T-72B3
~90 T-72B1
~725-756 T-72BA
~200-400 T-80U (know, large discrepancies)
so at least circa 1500 tanks in active servise and after repairs or worn but relatively young
Of course apar this above we have circa 500 T-80BW and some number of the T-72B (again circa 500) but status is not sure.
Poland:
In Poland we have sucht tank batallions in units:
- 1.Warszawska Brygada Pancerna im. Bohaterów Westerplatte - (1 battalion PT-91)
- 21.Brygada Strzelców Podhalańskich im.gen.bryg.Mieczysława Boruty-Spiechowicza - (1 battalion T-72M1)
- 10.Brygada Kawalerii Pancernej im.gen.broni Stanisława Maczka - (2 battalions Leopard 2A4)
- 34.Brygada Kawalerii Pancernej im. Hetmana Wielkiego Koronnego Jana Zamoyskiego - (2 battalions PT-91 (soon ex german 2A5)
- 2.Brygada Zmechanizowana Legionów im.Marszałka Józefa Piłsudskiego - (1 battalion PT-91)
- 9.Brygada Kawalerii Pancernej im.Króla Stefana Batorego - (2 battalions T-72M)
- 15. Giżycka Brygada Zmechanizowana im.Zawiszy Czarnego - (1 battalion T-72M)
- 20.Bartoszycka Brygada Zmechanizowana im.Hetmana Polnego Litewskiego Wincentego Gosiewskiego - (1 battalion T-72M)
In Poland they are two structures about tank nubers in tank batalions
I structure - 58 tanks in batalion (Leopard-2)
II structure - 53 tanks in batalion (T-72M1/PT-91)
So now we have:
2x Leopard-2A4 batallions eacht with 58 tanks, so 2x58 = 116
4x PT-91 batallions eacht whit 53 tanks, so 4x53 = 212
5x T-72M1 battalions eacht whit 53 tanks, so 5x53 = 265
So in theory in active service it will be
now 593 tanks, BUT there are some additional tanks in trening units or others -for example 12 Leopard-2A4 in tank school or simmilar PT-91 number in other tank school, etc.
So whole tank number is over 620 tanks.
---------------------------------------------------------------------
In close future two ex-german Leopard-2A5 battalions will be ready and moved to 34.Armoured Cavalery Bde. so used there now PT-91 will be moved to other units, and part (or all) T-72M1 will be withdrawn.
Wery soon (2015) in Polish Armoured Corps will be:
4x Leopard-2A4PL/2A5 batallions eacht with 58 tanks, so 4x58 = 232 Leoprds + aditional ~15 tanks
4x PT-91 batallions eacht whit 53 tanks, so 4x53 = 212 + aditional circa 12 tanks
And this is sure minimum number of tanks: 444 in service + circa 26-28 in other units so whole number 470 tanks.
Future of the T-72M1 is unkown - at least two batallions will be withdrawn so T-72M1 number will be definetly under 159,
but it's very possible that all T-72M1 will be withdrawn without successor before 2018 -due to budgetary matters, and structural reforms in Polish Army.
