You should make the difference between the arab soldier and the usa soldier greater. Otherwise it will be hard to play (because of friendly fire ^^).
A video of your scripting process would be interesting!
That's why I changed the soldier colours, but anyway It can be changed in the future
What I find especially interesting is the third person thing.
Do you already have methods for fluid and accurate camera movement and aiming?
And how do you handle animation blending with different animation sequences for upper body/lower body?
The camera point of view is this:
As you can see it's and hybrid between standard 3rd person view and 3rd person aiming, with mouse_right you can zoom a bit.
About blending animations, I use ent_bonerotate for the shoot animation (it's done by script) and then it's mixed with ent_animate with walk, run or idle animations.
