Isn't it assumed Egypt in this scenario as in the OTL has HAS?
You got me there. What is Egyptian HAS?
One problem is the poor maneuverability of the MIG-23MS and poor endurance of the MIG-21.
Aircraft that rely on high speed, rather than on maneuverability will be flown like IADF did with OTL Mirage III - use high speed to dictate entry and exit from air combat, and employ 'barrel roll' against slower fighters.
MiG-21 still has enough of endurance to be flown against Egypt close to the Suez Channel, and against Syria above southern Lebanon and Golan heights.
I think one big change in IDAF doctrine will be that it will be more defense oriented , as Soviet aircraft have roughly half the range or less of contemporary western
Flip side Israel mat get a ton of SAM systems like arabs got
Thirdly the lower cost of Soviet airplanes mean they will numerically be a little better position
I was more interested in the tactics Israelis may develop to use the cumbersome yet fast mig23/25 , any suggestions?
IDAF going on defense means yielding initiative to a more numerous opponent - not a good scenario for Israel.
For fast jets like MiG 23 or 25, use the same tactics as with Mirage III per OTL. video (low quality)
