Mortars...
507 60mm Mortar Sec - there weren't any 60 mm mortars in Poland before 2001 - so it should be removed (see below).
508 60mm Mortar Sec - introduced only in 2001 (now 1/70) [
http://www.militarium.net/viewart.php?aid=173 and other sorces].
It would need changes in formations 314 and 270. Maybe 270 should be available from 2001, and ending date of 269 should be extended.
According to Polish MoD page, standard unit of ammo is 40 (now 60).
82mm mortars were earlier used by the Polish paras (weight 56 kg), but I don't know in what formations.
As for weapon #030 60mm LM-60D Mtr - according to MoD page and other Polish sources max range is only 2329 m (47) - now: 60.
511 82mm Mortar Sec - crew's weapon in this period should be 06 SMG instead of bolt rifle (earlier it would be probable as well)
513 82mm Mortar Sec - crew's weapon should be Beryl rifle (028) instead of Beryl SMG (limited use).
515 2x120mm Mortars - might as well be armed with #42 120mm M43 Mtr - both were used from the beginning, and have essentially the same specs. Weapon #246 PM obr38 is redundant then (it has too small min. range (3) - it should be 450-460m, just like #42). Better picture is 29425 - current is some Western mortar with integral wheels.
516 2x120mm Mortars - as above. Crew's weapon in this period should be 06 SMG instead of bolt rifle (earlier it would be probable as well)
517 2x120mm Mortars - standard crew's weapon in this period should be general issue AKMS (029), not SMG. Better picture is 29425. It should be used until 115-120 - there are no newer mortars as for now (now: 12/99)
520 2x160mm Mortars - used only from 1951 (1/46), according to J. Kajetanowicz. Crew's weapon should be 06 SMG in that period.
It would need changes in form. 209 - first date 1951, last - 1979? (see below)
521 2x160mm Mortars - crew's weapon should be 06 SMG
523 2x160mm Mortars - they sure weren't used in that period (90-96) - withdrawn well before this date, but I have no closer info. Probably late 1970s.
525 2x120mm Mortars - there are no new 120mm mortars as for now - possible date is 2013 (there is a new mortar M120 developed
http://pl.wikipedia.org/wiki/HSW_M120 but not produced so far). Icon should be 67, pic - 29425.
Weapon 164 120mm M120 Mtr has too small min range (4) - it should be 9-10 (480 m)
527 120mmM43 Mortar - standard crew's weapon is general issue AKMS (029), not SMG (what is confirmed by photos). Picture should be 29425 (now it's 160mm).
528 120mmM43 Mortar - crew's weapon should be Beryl rifle (028) instead of limited issue Beryl SMG. It should be available until 115 at least (now 12/99). Picture should be 29425 (now it's 160mm).
529 120mmM120 Mort - there are no new 120mm mortars as for now - see notes for #525 - possible date 2013.
There could be added
120mm 2B11 mortar (weapon no 44) used in limited quantity (radio 91) from 1984. Secondary weapon should be AKMS (29), crew 6 men.
533 Observer Team - redundant unit - Onyks SMG wasn't used.
