Rest:
232 Ammo Truck - better picture is 29388 - Polish modern Jelcz.
236 WZT-1 - as a standard, it has no dozer - this is ARV, not engineer tank. Useless IMO.
237 WZT-2 - commissioned in 1979 (now 1/78) [Poligon 5/2010]
238 WZT-3 - commissioned in 1989 (now 1/105) [Poligon 5/2010 and others]. Armour of this ARRV should be definitely no better, than basic T-72M tank (#16), if not worse. AAMG should be 017 NSVT. Full name (rarely used though) is WZT-3 Bizon. Correct picture is 29531 (confused with MID). It might have 3 or 4 SD (now 2) - it has 12 tubes.
239 IWT - only 5 prototypes were made around 1976 [Poligon 5/2010] and used for a short time. Full name is IWT Klon. Might be removed - or made available until end of 1980s at best, with radio 1 or 3.
240 MID (engineer tank) - armour should be definitely no better, than basic T-72M tank (#16), if not worse. AAMG should be 017 NSVT. Correct picture is 29383 (confused with WZT-3). Full name (rarely used) is MID Bizon-S. Used in limited numbers from 1998 or even earlier (1/08) - should have radio 91 [Raport 10/98]
In a free time, there could be created new icon for MID and future WZT-4, with a crane on the right.
BTW: MID-M variant, with .50 AAMG, should be also used by Malaysia from 2009.
241 T-34/85 WPT (ammo carrier) - it was ARRV, not supposed as ammo carrier, and without much room for ammo. Anyway, proper name is WPT-34 and they were produced only from mid-60s (now: 1/50) [Poligon 5/2010]. To be removed IMO - useless.
243 Headquarters - should be rather armed with general issue 008 rifle, not SMG - and be available until 120 (or until next unit)
244 Headquarters - wz.89 Onyks SMG wasn't adopted to service. Should be armed with general issue 029 AKM(S) rifle, and be available from some 1965 (now: 1/90).
245 Headquarters - it should have general issue 028 Beryl rifle - Beryl SMG wasn't widely adopted.
249 Crew - better picture is 14249 (TT, used until 1970s, instead of some German one)
280 Formoza Navy SF - in fact, frogmen special unit, nicknamed Formoza (later it became an official name), was created in 1976. First unit (might be this one) should use ordinary 029 AKM(S) rifle, especially, that Onyks SMG wasn't adopted.
283 Formoza Navy SF - wz.2003 LMG wasn't commissioned - it was to be a Polish equivalent of Minimi. In fact, redundant unit because of 282. Wz.2003 LMG might be replaced in weapons file with Minimi Para, used by special forces, but I don't know if it makes sense, considering its narrow usage. In that case, in other units wz.2003 LMG should be replaced with 16 UKM-2000 LMG
290 Special Forces - early Special Forces would sure use 006 SMG instead of a bolt rifle. RPG-2 was used only from 1953 - earlier there were grenades only. Next unit
291 could be made available from 1953, and P-27 Pancerovka (briefly used) should be replaced with RPG-2
300 Rifle Section - Panzerfaust were very scarse, not used in infantry sections [Poligon 2/2011]. Should be replaced with AT grenades.
305 Cavalry Section - primary armament should be probably PPSh SMG #09, not LMG
I don't think, that cavalry sections carried 7-feet-long PTRD on horses... (AT grenades rather)
314, 315 Mech Rifle Sec - P-27 should be replaced with standard RPG-2.
317 Rifle Section - it seems improbable, that in 55-79 there would exist regular infantry sections without LMG (there were plenty of them, especially from beginning of 1950s.)
329 Rifle Section - AFAIK in 1980-99 there doesn't exist regular infantry without LMG in section. In all units 328-331 there should be 013 PKM LMG.
336 Rifle Section - definitely there doesn't exist in 100-120 regular infantry without LMG in a section. In all units 325-338 there should be 016 UKM-2000 LMG.
I have no time now to check precisely structure of infantry platoons in the game, but sections without LMG should be definitely wiped out.
360 Naval Infantry - was created in 1951 (now 1/55) [Raport 8/07] - needs change in formation.
365 Pe-2 Peszka - more precise name is Pe-2FT Peszka (though Peszka is informal and might be left out). Ithas too much load - it could carry 10x 100 kg OR 4x250 bombs (now: 6x100, 4x250) - max 1000 kg.
It could be fighter-bomber as well - in fact it was a dive bomber. It would have 1x #175 12.7mm UBS and 1x #174 7.62mm then.
366, 367 Il-28 - delivered in 10/52 (operational from some 1/53), used only until 77. Needs change of formation's last date.
368, 374 Su-20MK - name was just Su-20 (Su-17MK was Russian designation). Withdrawn in 2/97. Proper picture of the Polish Su-20 is 29126 (now it's Su-22)
376 B10 RCL HE - used from 1/55 (1/50) until 1980s (12/99)
378 SPG9 RCL HE - apparently still in service, possibly until 120 (12/94). Better rifle is 029 AKM(S)
380 82mm Vasilek - it's a detail, but better icon seems 54.
400 White Scout Car - PTRD ATR might have been used on some vehicles during the war, but it was withdrawn from the Polish service by 1948 (see #370). Most probable weapon is just one DT AAMG - DShK was quite bulky weapon and it didn't automatically replace .50 Browning on vehicles.
401 BA-64 in 12/54 there were 97 BA-64 in inventory - I doubt if they were withdrawn that month. A weapon had high elevation - #242 AAMG could be more approproiate (for all countries). Most have no radio.
