Ok now I'm really going to jump off the cliff, why not bring back an old beast like the A-1 Skyraider? Could you imagine being on the receiving end of something like that dump truck of death? Now I know that the SPAD is long gone, but why not a shit hot turboprop that can haul a lot of stuff and have some serious loiter time? This looks cool...
EMB-314 Super Tucano
I think a Marine could plop this on an Amphib.
My flak and kevlar are on and I'm waiting on the mortars.
