True, but basic prosthesis and flame weapons are pretty easy for GDI to develop, so you can probably build your own flame tank and prosthesis if you have the designs. But Tiberium research is where GDI and much of Humanity draws the line. As General Granger from C&C3 said "That's not who we are, that's not GDI." So no Tiberium research without facing jail time.
Tiberium research is far more than infusing it into people you know that right? Most Research is in using it for materials, power, and weapons technology not for transhuman BS that NOD got up to.
I think it is safe to say that GDI knows all they know about Guerilla fighting from the decades of having to deal with Nod but they aren't the masters of it like Nod was. It should be noted that the Turians would level a city block just to take out a squad so whenever there is a battle, it is very likely the Turians will bombard the area they are fighting in with extreme prejudice. Stealth won't matter if the enemy just nukes your army.
They will not be using WMDs at all for one that fleet wouldn't have them with them and two they have rules they follow.
Not really, the wiki mentioned that the Turians will level a city block by orbital strike if they saw human defenders. The mountains aren't going to help since those strike are pretty dang precise. Underground cities are much better defended from orbital strikes but are expensive and take a long time and Firestorm Shields can defend against Orbital Bombardment but it is expensive and guzzles a whole lot of power. But that is pretty reasonable for Orbital Protection.
They wouldn't use orbital strikes as they would get sanctioned and censured by the rest of the council. Unless you are going to railroad Saren's brother being a pawn of the Reapers already and their being a Reaper Artifact on the planet that was somehow completely missed that will not happen. Leveling a city block would be with conventional stikes and units not with warships which I should mention would destroy most of the city not the block. So no the Turians would not be doing orbital strikes unless those strikes are gunships and fighter strikes. Both of which are far less useful in a mountainous region. The Turians have rules and they follow those rules. Only when a commander is compromised or they are in a truly desperate situation (Reaper War Proper) would they ever think of doing that normally.
[X] Before the release of the Confession to the world, a Nod warlord, who is suspected to be a descendant of a Nod field officer during the 3rd Tiberium War, secretly offered a deal with GDI InOps. In return for amnesty, renouncing the Brotherhood of Nod religion, and signing a defensive alliance, the Liberated will help GDI hunt down rival Brotherhood splinter groups that continue to be loyal to Kane along with giving GDI access to various Nod technologies that they can use however they see fit. With the deal struck the new Liberated faction renounced Kane as an uncaring and ruthless mastermind that created the Brotherhood to serve his own plans, not the betterment on humanity. This caused the Brotherhood to have a massive schism with only a small number of minor warlords are antagonistic towards GDI. The rest either join the Liberated or surrendered into GDI custody.
(GDI gains access to Nod technology, the Liberated is a tentative yet public ally in helping GDI keep the peace, Friction between Liberated and GDI are common as 5 decades of conflict doesn't just go away, ???)
[X] Mountainous, plenty of tall mountains and hills that makes this an ideal mining colony. You'll most likely have to be careful with this one, Tanks can't jump over sheer cliffs like the infantry yet so I advise investing with Mobile Infantry, VTOL Aircraft, and Hover vehicles to be able to maneuver around the area effectively.
