It seems to me that there is a reason why IAF requested those odds. It seems that they wanted to stimulate an PAF-IAF encounter with USAF acting as the PAF. I guess they want to validate their tactics for future battles with PAF. It makes sense because USAF is the premier air force in the world and would have better aerial dogfighting skills than PAF. See how IAF requested USAF not using AMRAAMs or BVR missiles? PAF doesn’t have those and they have inferior numbers against IAF.
Looks like IAF baited USAF to be the red force in a stimulated war scenario without USAF knowing it!
