FAF or Korey Miracle, former FAF CEO, asked if GPEO would be interested in conducting ArmA-3 battles against them.
This would work well for the Hawaii land operations.
Rules ? For the scenarios, yes.
On Hawaii, in the VR-World, there are no armored units. Air Power is limited for those who have it in FSX. ArmA-2 most likely will be the best for land battles though, but ArmA-3 also if desired. Most of the time it will be infantry only, with few land vehicles, and those would mostly be for transportation, not fighting, as in, no weapons mounted. Rotary transportation also limited for both sides. GPEO, in Hawaii, would have Rotary transport ability.
