Bro why is the A-10 so fragile

Specifically the lack of damage it can tank. Especially around the tail. Why is the A-10 the only aircraft that if any part of the tail gets damaged all of the controls fail? The A-10 is built with manual override and secondary controls lol and it makes no sense that the entire tail fails when a singular cannon round touches ANY part of the tail. Not to mention the fact that the tail feels so much weaker than the rest of the plane. I cannot be the only one noticing this
