During MSPO 2022 in Kielce, Poland, I talked with GDLS and US Army representatives, all 250 M1A2SEPv3's for Poland will be new builds, not older tanks upgraded. GDLS still have capability to build new tanks. This was Polish Army requirement, that all these tanks will be 100% brand new, which I also confirmed with spokesman of Armaments Agency responsible for procurement with Land Forces Inspectorate.

M1A1's in long term storage are mostly empty shells, that either way will need refurbishment, overhaul and at least partial modernization before they can be fielded by any army out there that might buy them. Poland procured 116 M1A1FEP tanks with SCWS (Stabilized Commander Weapon Station) with AIDATS (Abrams Integrated Display And Targeting System) with slew-to-cue and RTS thermal sight with 3x, 6x and 9x magnification. So this works like CITV and gives commander hunter killer capability. These tanks also have BMS terminal and will use Sitaware BMS which was choosen for Polish Army M1 tanks. Poland also procured 250 new build M1A2SEPv3 tanks. In future it is planned to upgrade these 116 M1A1FEP tanks to M1A2SEPv3 standard. Polish Army also plans to procure APS for M1 tanks, probably Trophy HV. Deliveries of M1 tanks for Polish Army looks like this: 2023-2024 - 116 M1A1FEP. 2024/2025-2026 - 250 M1A2SEPv3.

President Biden was rather open about that, no M1's for Ukraine. M1 KE protection was ok when it was fielded. M1IP and M1A1 protection levels for both turret and hull front were improved, by how much? I don't know, but in my opinion it was around ~500-600mm vs KE +/- so just like in SBProPe. Majority of M1A1's were upgraded with Heavy Armor Package (HAP), either being upgraded to M1A1HA standard, or M1A1AIMv1 or M1A1AIMv2/M1A1SA. However in 2010 or 2011, Heavy Armor Package was replaced by Next Generation Armor Package (NGAP), we can recognize it by letter after serial number on turret side. Heavy Armor Package is marked with letter U, Next Generation Armor Package is marked with letter M. So from 2010/2011 onwards M1A1SA's and M1A2SEPv2's received 1st generation NGAP, while from 2018 onwards, M1A2SEPv3's have 2nd generation NGAP. All M1 tanks going through major overhauls receive new armor package. This is something to be confirmed this year when Polish Army will receive it's M1A1FEP's, however we know that after overhaul process, these will not be M1A1FEP's but, something we can call M1A1PL, and these might receive new armor package as well as other modifications to meet Polish Army requirements.

The only semi reliable source on Leopard 2 B tech and C tech armor protection, are some documents found in British archives, from British tests of Leopard 2. However I have only fragments of these documents that were posted in the internet.

And again to what made up values? Ballisticians in War and Peace volume 3 gives some information. Primary informations is, both M1IP and M1A1 got improved armor over basic M1. Both M1IP and M1A1 received something called KE Backpacks. Another provided information is that M1A2 have 35% better protection vs KE and 25% better protection vs CE for it's front hull armor over basic M1A1.

Eh, it all depends on what type of armor specific western tank uses. Up untill late 80's all Leopard 2, Leopard 2A1/A2/A3/A4 used B tech armor. Around 1986-1988 it was replaced by C tech armor and last batch of Leopard 2A4's is said to use D tech armor, altough this is not certain if it means main armor upgrade + new side skirts or only new side skirts.

https://www.gov.pl/web/obrona-narodowa/podpisanie-umowy-na-dodatkowe-116-abramsow-dla-wojska-polskiego Tommorow Polish MoD will sign procurement contract for 116 M1A1FEP tanks and support equipment. This year we should also have first contract for series production of Borsuk IFV.

@Ssnake I found interesting patent document. https://www.fips.ru/ofpstorage/Doc/IZPM/RUNWC1/000/000/002/781/472/ИЗ-02781472-00001/document.pdf It says that 30mm 2A42 autocannon have problems firing 3UBR8 APDS (and presumably also newer 3UBR11 APFSDS?), it is caused by interference of muzzle break with round (sabot issue?), causing drastic increase in projectiles spread, that is around 1m or more at 100m. Solution found was to bore out muzzle break by 1-2mm, then projectiles spread increases to acceptable levels. However it is not known if this modification is widespread. In Ukraine it seems that BMP-2's and BMD-2's use mostly 3UBR6 APBC. These problems are not present with 2A72 30mm autocannon because it lacks muzzle break.

Leopard 2's will stay in service untill enough K2PL's won't be procured, after that, all Leopard 2's will be withdrawn from active service. As for Abrams, currently we lease 28 M1A2SEPv2's from US Army for training purposes, on order are 116 refurbished M1A1SA's and 250 brand new M1A2SEPv3's, in future more might be ordered. M1A1SA's are planned to be upgraded to M1A2SEPv3 standard at some point in future.

Actually we ordered 180 K2's, and with Korea we are developing K2PL which we plan to procure around 820 so in total there will be 1000 K2 and K2PL tanks in Polish Army as per current MoD plans.

So, there are still some T-72's used by Polish Army, not all were sent to Ukraine. Now the questions is, how many we really had? Polish MoD really like to make everything a secret.
