Realistic Low-Poly FPS Soldier Model

We are developing a mobile FPS game and need a low-poly Realistic tactical soldier character.

The character must be optimized for mobile performance and compatible with Unreal Engine.

Since this is an FPS game, the hands, fingers, and face must look clean and well-designed.

Requirements
1) Blender source files (.blend) must be included
2) Character rig must use UE4 Skeleton
3) FPS arm model must use UE4 Male Skeleton
4) Vertices/Triangles up to 5k (around 3k preferred, but maximum 5k acceptable)

Additional Notes:-
The character must be game-ready and optimized for mobile
Clean topology and proper UV mapping
Good detail on hands, fingers, and face

Deliverables:-
Full character model
FPS arms model
Blender source files
Rigged with UE4 skeleton
Optimized low-poly mesh
