OK here's what I know for sure.. )..
.... in a test scenario I had already set up to test standoff attacks there was a coy of Iraqi tanks for targets. I opened the scenario from the Iraqi side and selected a tank. I clicked on the unit leader tab and then clicked on RANK and entered 713 and surprise, surprise, surprise.......'Arif Anwar was transformed to
Sergeant Anwar and entering 720 makes him a Brig-General
NO it does not change his ratings but it does change the rank that is displayed but again.......changing his rank does NOTHING to his rating but 713 and 720 works as predicted
but that is where the wheels fall off 740 makes that leader a "P.Plukov" which is only in two OOB's none of which have anything to do with OOB 7 but rather one or the other slovakias in OOB37 or OOB51 and I can say with some confidence that in the 18 years I've been doing this....this is the first time this has been brought up ( which is why the bug lay dormant for so long )
further digging shows 810 which I thought might give PLO ranks instead gives TaeRyong which is a South Korean Colonel......go figure how 713 gives a Brit Sergeant rank and 810 a South Korean Colonel......I'd love to see how the math works for that because 810 -713 = 97 and there are more than 97 individual ranks between Sergeant on the brit ranks list and the South Korean Colonel.
What should happen...(and I predict is will happen after the next patch)....is you should only be able to enter numbers between and including 0 and 10 and you will get the rank name FOR THAT OOB............entering 713 and getting Sergeant is a bug that in that one case actually fit a theory but 613 won't get you a French rank it gets you an Afghan rank
Fun
