There are some issue with the availability dates of soviet weapons.
The mistake the OOB designer did was assuming that Iraq purchased soviet weapons in the postwar period. In reality this only happened after a coup which took place in 1958. Before that Iraq was strictly an US-UK client and the UK was the main source of arms.
Units 1-15-16-41-574-572-570-349-347-345-330-311-211 are AFVs. Their availability date should be changed to to february of 59.
The first shipment of armor, together with the related advisors and tech support,arrived in february of 1959.
It was composed mostly of T-34-85 but others types were present. T-54 were noted in a british intelligence report dated march 1961 and may have been shipped together with the T-34s and the SU-100s.
The following are artillery units 53-76-86-93-101-103-171-173-177-231-232-235-238-266-296-297-307-309-428-430-550.
January or february of 1959 should be an appropriate starting date.
Units 138-140-153-187-255 are aircrafts. The first planes were delivered at the end of 1958, not at the beginning.
In any case if at least a minimum of familiarization time is allowed january 1959 should be an appropriate
starting date.
Unit 340-341 JSIII. They should be eliminated. If not availability date should be changed to 2 of 1959.
