WI ground support aircraft (like the A-10 or the Hawker Typhoon) were not seen as being as necessary as they are IOTL, and thus aren't really built all that much?
How would this change the Cold War and the rest of history? I've heard stories of how badly Russian tank crews were afraid of the A-10; would the lack of such an aircraft change anything?
Without any other dedicated ground support aircraft to go off of, what would the first one look like? Please don't say "exactly like the A-10."
