Once again M7 has traveled to another great national event. This OP.........Oklahoma Invasion 6. OKI is by far the best and most realistic you can get out of MILSIM. Here is a teaser trailer for our up and coming "Oklahoma Invasion 6 Documentary". Our position in this event was a SOG Air Mobile Unit , we used a helo for our insertions/extractions from battles as well as doing gun runs over enemy encampments.
