049 Vickers Mk.6b - I've checked, and only 88 Vickers Mk.VIc were made, with some 900 Mk.VIb, so VIb is more probable. But I wouldn't suspect, that Iraqi weapons file is so crowded...
065 BRM-1 - I see. However, number of troops carried might be lowered and we could create some nice formation with scout vehicles and scouts (I haven't noticed such unit).
As for BRM-1K export, Russian sources say, that they were exported "mainly" to Warsaw Pact countries - so we can't be sure :-) However, Poland and CS received them only in late 80s.
281 BA-64 - I think it can be removed. They were withdrawn from the Soviet Army by mid-50s and would be rather worn-out, while they could export newly produced BTR-40.
As for BRDM-2 with 23 mm gun - I think we could add one. Authors like Zaloga write about "some" vehicles rearmed, so I think it's worth adding, even if there were few.
316 OT-64C SKOT - I think, we can safely remove this one.
Further thoughts:
225 BRDM-1 Shmel - I'm pretty sure, that Iraq hadn't them, but I can't prove it :-( A Russian page
http://cris9.narod.ru/rva_2p27.htm says, that they were exported to Warsaw Pact countries, but it is known, that Cuba had them as well. I've read somewhere, that BRDM with Shmel were never used in combat. Anyway, proper picture is 29057.
227 BRDM-2 Konkurs - proper pic is 29253. According to Russian sources, it carries 15 missiles (now: 10).
