To be fair, C&C4 is the garbage timeline, where tiberium spread went to shit and Kane showed up at a GDI Council meeting with the Tacitus going "I can solve your Tiberium problems. Shall we make a deal?" and GDI agreed. "Dump it on a red zone" might be dumping it one block over.
...Dump it on a
distant Red Zone. The point is, this is less of a pain in the ass than launching it to escape velocity,
GAH!
I think we just have a perspective issue here. I've been thinking of ZOCOM as a red zone offensive command. You, probably more accurately, see it as a general red zone operations command.
Well, think about it.
Nod doesn't
live in the Red Zones. No one can. We've had it explicitly confirmed that when Nod tries to operate in a Red Zone, they generally end up having to write off a lot of valuable equipment (and potentially
people) because of tiberium contamination. Even they aren't immune, though they surely have their own equivalents of T-Glass and so on.
So ZOCOM probably spends a significant amount of time guarding stuff that isn't,
at that particular moment, under attack. Because no one else can do that job, no one else can guard that stuff, because...
So from my perspective, Zone GF could be used to take over "quiet" RZ garrison duties (as opposed to the "hot" garrison spots) from ZOCOM, allowing ZOCOM to put more troops into offensive work elsewhere. I figure the Zone GF would get the survival training, but not the tactical training, etc. So while they can handle RZ duties, they just use slightly adapted conventional tactics rather than the highly adapted tactics of ZOCOM.
The problem is that the survival training... and importantly, survival
equipment, which means not just the power armor but the environmentally sealed everything, the hover-vehicles that can drive over a tiberium patch and not have to be scrapped because the running gear turns into a solid mass of tiberium within a few days, stuff like that...
All that survival stuff is probably the single biggest point of divergence between ZOCOM and Ground Forces. By the time you take a Ground Force unit and train and equip them to (1) operate power armor and (2) to survive in a Red Zone,
you have effectively got a ZOCOM unit.
So I just don't think we're going to see much Ground Force deployment into Red Zones, except perhaps for very specific duties at the very fringes of a Red Zone territory providing flank security for one of our big Red Zone 'offensive' harvesting operations
The trend is going to be that Ground Forces operates
up to the Red Zones, while ZOCOM operates
in the Red Zones. Historically, ZOCOM tended to operate heavily in the Yellow Zones as well, but that was up to and during Tib War III, when there were more of them and when GDI very rarely actually bothered doing much in the Yellow Zones, so you could have nothing but elite strike units to do anything there and it wouldn't matter because the tempo of Yellow Zone operations was low. By contrast, postwar GDI in the quest timeline has aggressively pushed forward into the Yellow Zones and has built up plenty of experience fighting and building in those conditions... But the Red Zones are just so incredibly much worse that it would be madness to try to take a force equipped and trained for
general ground warfare in the parts of the Earth humans can still more or less survive in, and expect them to be reliable garrison troops for the uninhabitable,
rarely Nod-assaulted Red Zone regions.
What will really reduce the pressure on ZOCOM is the use of power armored Ground Force units to do the
Yellow Zone stuff ZOCOM has historically been doing ever since before the Third Tiberium War.
