In the first image it is seen US Soldier is on high alert as if going to act immediately and there are two Apache Helicopters behind him in the sky.

The second image seems that the US soldier is looking like the SCAR-H. Also notice the helicopter flying and the white mountains.

Don’t start guessing of any underwater war with the third pic. It is just an intro.

The fourth image seems as if the US soldier is with modified ACR. Next image shows British SAS dropped on the soil of Russia. The last image is SEALs in Combat Rubber Raiding Craft (CRRC).
