Don't forget to run deep if your being harassed by a Mark 24 from an aircraft. They will home in on you and kill you within 30 meters of the surface.
If your up for it add OMEGU mods for better environments.

Make sure your mod order is :
OM v705
OM v720
OM v720 Patch 5
OMEGU v300
OMEGU v300 Patch 7
If you add OMEGU do not switch side back to the americans.
