- They are without doubt the strongest ground force.
- A well rounded faction that aren't seriously lacking in any area.
- With free special powers they have a lot of reinforcements available.

- Mammoths have repair drones.
- GDI are the only faction that can garrison their own buildings.

- Firehawks carry both AA missiles and AG missiles. The AA missiles auto reload but the AG missiles are only reloadable at the airfield.
- Battlebases are much stronger now and receive the railgun upgrade when it's researched.
- GDI can build a HAZMAT Disposal Facility. It provides money like a tiberium spike and acts as a silo.
