Nothing will survive a lethal attack. Not the A-10 or the F-35 or the F-22. Not an Abrams tank; not a Patriot missile battery; not any helicopter.
Not a soldier. Not an aircraft carrier. Not an ICBM launch site.
That said, it doesn't mean these things are not essential.
The goal of the military is, first, prevent wars. Second, win those that get started. To win a military has to destroy the enemy at a rate the enemy can't sustain while taking losses at a rate it can sustain.
If used, A-10s will be at risk; so will every other weapon system.
Not to sound condescending, but your statement is self evident. In my post I was wondering if something has happened on the fields of Ukraine that make using the A10 more dangerous to fly—more susceptible to destruction—than has been deemed acceptable?
The US doesn’t use suicide missions as part of their doctrine.
