Probably C-130 Hercules. They are about the only large turboprop left in the USAF inventory. Used for battlefield conditions. Some are armed with miniguns and Vulcan cannon and used for direct ground support.
My guess would be that we are planning something big that will take time. Folks are thinking this will be over before the leaves fall. Or by Christmas at the latest.
Wrong.
Think WWII.
Q. How much time elapsed between Pearl Harbor and the first US raid on Japan (the Doolittle Raid, specifically)?
Look it up, chilluns -- it is relevant to the time this new war will consume.
