It's right to remove KPVT from SU-100, but has anybody seen a photo of SU-100 (especially in Iraqi service) with any AAMG?...

Nope. But it gives it a bit of extra flexibility game wise and since I have seen only limited photographic evidence of iraqi SU-100s

I did not feel like cutting it out, particularly as they seem to have bolted additional AA weapons on a number of chassis. I'd recon it could be argued either way.

049 Vickers Mk.6b - current armament is of Mk.VIc variant (by the way, Roman numerals were only used). Mk.VIb was armed with 0.5 in Vickers TMG (a bit worse, than 0.5 Browning) and 0.303 Vickers CMG (eg. #73 Vickers CMG from EGY OOB). I don't know which version Iraq used, but Mk.VIb was more common and is pictured.

From what I recall, but I am only going by memory, those iraqi Vickers were scrapyard items which the iraqis recovered, repaired and rearmed with whatever was available, in some cases 15mm Besa, in others only 0.303s. Keep also in mind that there are very few weapon slots left so one has to be careful which weapons to add.

065, 072 BRM-1 - If it's meant to be real Russian recce BRM-1K, then it needs modification, because now it's just BMP-1 with reduced armament. BRM-1K had a laser RF, ground radar and 2 SD, proper pic 11488 (only unit 72 has GSR). According to Russian sources (Bronekollektsya and others), it had 20 rounds for a gun only. Crew should be 4 + only 2 scouts, not 3+109 (might be 3+3, then we could create a formation with BRM carrying scouts - same for BRDM and other scout vehicles).

These were originally redundant BMP-1s with some off stats. I suggested them to be modified into BRMs, since that was what they were closer to. From what I read at that time not every BRM was fitted with GSR and given the role I would expect the LRF to be an add on, rather than integrated into the gunner sight.
The alternatve would have been deleting them but I have no idea if they were actually exported to Iraq or not.

281 BA-64 - actually, it had AAMG (open turret, high elevation). But were they really exported to Iraq? I couldn't find confirmation in Russian sources (mentioning Yugoslavia, Korea and China). Production ceased in 1946, so it would be hard to find working machines in 1959.

Like for a number of other items there is no way to tell either way, short perhaps of digging in some russian archive or interviewing some old iraqi. Personally I thought it was not exported but I could not be sure and I had a long list of more urgent changes.

288 BRDM-2 - if we make it class:scout vehicle, than it's worth to use them in formations carrying scouts (now: armoured car)

There is alredy a BRDM-2 classed as scout vehicle in a formation with dismounts available.

301 BRDM-2b (unused) - it could be changed to interesting Iraqi modification with 23 mm gun, used in 80s

I am not sure it was actually produced beyond prototype stage.

330, 331 TO-54, TO-55 - it needs confirmation, if Iraq used flame tanks. Russian sources don't mention, that they were ever exported, while numbers of built tanks weren't big. It's doubtful IMO

Me neither, but everyone has them and that flamethrower T-62 which probably never existed to boot.
