Iraq 1991: Replace USA with USSR

Here’s an interesting scenario.

Scenario is same as what happened in Persian Gulf War 1991 except for two key scenarios:

1. Instead of USA, we have USSR being the lead coalition partner.

This assumes deployment of high end Soviet units with better equipment (e.g. Su-27P, MiG-23MLD, full spec MiG-29), Su-17M4, Su-24, Su-25)

They also have standard Soviet support in terms of ECM and EW.

They’re operating out of Saudi airbases as well.

No Western aircraft are being used.

2. Iraq is primarily equipped with Western aircraft – F-4D/E (in place of MiG-23), Mirage F1, F-5E/F in place of MiG-21, F-15A/B in place of MiG-25 and F-16C/D Blk 30 in place of MiG-29.

Jaguars replace Su-20/22s.

Also Iraq’s doctrine is assumed to be British, not Soviet, and is assumed to have gone to war in 1980-88 with a Soviet equipped Iran with similar results.

Political situation is same.

Questions

Could the Soviets have managed to suppress Iraqi air defences as effectively as USA?

Would Soviet pilots have been able to manage to obtain air superiority as quickly and as effectively as US ones?

Would Soviet casualty rates have been higher?
