Weapons the War in Ukraine Is Proving Obsolete
What you don't see in Ukraine: competent employment of combined arms.
The A10 aircraft is specifically called out as obsolete, but it is a great bomb truck. While it may be a sitting duck for a new fast jet, a more realistic mode of employment would be to tie it in with F35s or similar when in a near peer conflict.

Of course, most conflicts are not going to be near peer, so getting rid of something as useful for armed overwatch as A10s makes little sense.
