"Nearly all of the US aircraft based at RAF Lakenheath operate on ultra high frequency (UHF) radio and cannot hear civilian aircraft, which use very high frequency (VHF)."

A-10C has both UHF and 2 VHF radios. You can tune into both at the same time.

Was just reading a book about Air America and they had the same issue in Vietnam where all of the mil traffic was on UHF. It did lead to some accidents so it's nothing new
