It would be like France loosing half its marsouins and chasseurs alpins, and 80% of the legion in a week. A disaster.
And the worse is that Ukrainian migs are still flying over occupied territory. That's unforgivable. It's the proof that the fox3 capabilities they were boasting about are in fact shit. Now they lost Thales for their optics and avionics, so that might be an explanation on why their engagement range for air to air combat seems limited, but this is a bad look.
