The picture shows quiet well, why this nonsense about squadron numbers is no real problem, since you only need 1 upgraded Mig 29 today to do the same mission, that you needed 1 Jag + 1 Mig back then. IAF should get rid of single role fighters like the Jags and Mig 27s, rather than wasting time and money on upgrads, that doesn't add more operational benefits. They already regret the money they wasted on upgrading 2 Mig 27 squads, which now have to be shelved as well, because they are technially far too unreliable anymore and they will regret the Jaguar upgrade soon as well.
