Polish OOB2 corrections/suggestions (v.6)

[Pibwl]

A bit more on artillery, mostly used by the Poles in North Africa:

401 25mm AT-Gun - should be available until 8/40 at least (the Polish Carpathian Bde took its guns from Syria to Palestine, and then lent them to the British).
Reportedly they were used until 1942 for training in the UK, but it's not worth adding I guess.

There should be added:
- 37mm AT-Gun available from some 1/41 until at least 5/42 - they were used in action at Tobruk (radio 92).
It could be copied from unit 400, but with #242 .303 rifle and maybe #88 Mills.

- 47mm AT-Gun - captured Italian Breda, available from 8/41 until some 5/42 (unit #578 in the British oob, along with its weapon).

- 20mm AA-Gun - captured Italian Breda, available from 8/41 until 5/42 (unit #748 in the British oob, along with its weapon).

- some Italian field guns used at Tobruk, presumably 75/32 FG (unit #029 from Italy, along with its weapon, with range corrected to 203 - 12.5 km) - used in 8/41 - 12/41 at least

- 65mm Mtn Gun used in 5/40 - ? (presumably 12/40)
It could be copied from unit 409, but with #176 Berthier rifle.
I've written before, that unit 409 should be available until 10/39 only (it has a Polish rifle BTW).

Formation 338 Infantry Guns should end at 10/39, and there should be another one in accordance with new unit, named Mountain guns.

- 18 Pdr Howitzer used around 8/40 - 5/41
(unit #127 from the British OOB, along with its weapon; radio 91)

There also could be added 75mm Mk.I FG (#627 in the British OOB), used for training in the UK, but not necessarily.
