Possinle artillery errors

[Imp]

Swedish OOB
Unit 430 - STRIX sec - has a penetration of 30

Also & no idea if there are errors but off board MLRS sections seem to have inconsistencies. Realise probably different versions but seems odd if use USA as the base due to the fact it has several choices I was wondering if the ones in German, British, French & Finnish OOBs have some errors.
Finnish unit 557 - Kill 50 Pen18 Range 252
French unit 562 - Kill 60 Pen18 Range 222
British unit 159 - Kill 60 Pen10 Range 222
German unit 112 - Kill 60 Pen18 Range 222

USA have no Pen 18 units & there HIMARS has identical stats to the British system but only 12 instead of 24 ammo per tube.

Also a possible thought regarding CM arty, due to rockets generally having a smaller warhead size than tubes should they have there penetration increased by 1 to stop them being less effective.
