GREYSOC has its own small-scale air force with jets and helicopters borrowed from the US government.
GREYSOC's current armament includes:
Blackhawks (both combat and medical)
Little birds
Ospreys
A-10 Thunderbolts (limited numbers)
Like the SUVs they drive, their aircraft are also unmarked.
GREYSOC will also tend to use civilian helicopters but this has only been observed a number of times.
