Several notes (of little importance) as for
Polish OOB, thanks to a new 2024 article on Polish armoured weapons from 1960s.
005 T-55A - used in a quantity from 1/69 (now 1/68)
714 T-55 - first series-built tanks commissioned in 1/65 (now 1/64) (only two T-55 were bought in 1/64 as licence patterns)
414 IS-2 - last units were disbanded in 1/64 (now 12/60), so a better ending date is 12/63.
Formations 12, 13 should be modified accordingly. Used afterwards for training.
025 SU-100
705 SU-85 - both withdrawn in 1963, so used until 12/62 (now 12/59), like formation 014 (no formation change needed).
058 FUG D422 - could be used from 1/64 (now 1/65) - first two were bought in 1963, and 50 during 1964.
It had no fixed weapons, but could be armed with some crew's LMG at least (eg. 010 7.62mm DPM LMG, if we accept infantry weapons in this role). Firing LMG from FUG through open top hatches was not different from BRDM-1 with a fixed MG anyway.
704 SU-76M - ending date 12/59 might be correct for the army... but it appears, that 127 of them were still used by Internal Security Corps (KBW) (
https://en.wikipedia.org/wiki/Internal_Security_Corps ), and in 1966 the army took them. There could be the second entry, say class 127 Gun APC (Tracked), wihdrawn by (probably) 1972, with 3-vehicle platoon eg. "Security SPG plt" (or KBW SPG up to 1965 and WOW SPG from 1966).
Speaking of KBW,
550 SU-57 were used after 1945 only by KBW, so they could be the same class.
I was surprised to learn that there was an APC variant of SU-76M:
TOSU-76, with a dismounted gun, used by the same formation, until 1972. It could be added, even with the same icon. There is no mention about the armament, but 242 7.62mm DT AAMG was plausible. I suppose it carried 4-5 men. I'd make it class 24 APC (halftrack) - they were used by the same KBW forces as existing 724 Halftrack. There is already a formation 11 Security HTs, which should be extended then (maybe renamed to Security APC).
Edit:
One more significant thing, from other article:
131 MiG-15 - now used from 1/50, but first 5 were delivered in 7/51, and a big batch in 10/51. I don't known when they were ready (no later than 1/52 anyway).
687 Lim-2 - now used until 12/74, but in 1968 there were only 13 left in attack units, so I guess they could go before 12/69 (we have newer Lim-6bis attack planes by that date)
130 Yak-23 - Polish name is Jak-23.
