Also a fact. Everything the USMC says they want to do with Reapers is just a bad idea. The stuff the airplane is really good at doesn't really overlap with the 6 functions of Marine Aviation.
The Marine Corps does not need the FBI surveillance van in the sky that is the Reaper.
What do you think the Corps is going to do with Reapers? I can tell you right now it doesn’t involve flying into a WEZ for collections that is already covered by NTM. Where along the spectrum of conflict do you envision these being used properly? What is the threat environment most pertinent to island chains? Do you think the littoral environment is more or less difficult in targeting as an urban environment? The Corps is not going to run around and try to F2T2EA an adversary’s Navy capital ships by ourselves.
This conversation rapidly goes classified to get into specifics. Long story short: I think you’re envisioning an environment 180 out from when and where these things are going to be used.
Marines will definitely need those F-35's and Reapers if they have to campaign in the Paracel and Spratly islands. Especially, where defending ground units might be spread thinly across many islands.
Those O-5 commanders will need the responsiveness & force multiplier effects these systems provide. Yes, they're expensive, but the Commandant chose those systems over tanks and tube artillery.
None of what you typed (bolded) is ever going to happen.
