Technically, from what i've understood from the sources. The SOW (Special Operations Wing) operated at rather high altitudes, to avoid enemy AAA. ZU-23-2 topped at about 2000 meters, ZPU-4 at about 5000 meters - but those are maximums, where are the projectiles far beyond their effectivity and accuracy.

The Spectres operated above this altitudes, targeting the enemy AAA positions and they were notably sucessful.

On other hand, the very-low airdrop that was performed by the Rangers at around 150m (500ft) prevented the AAA to fire at the MC-130s as they were mostly located on the elevated land around the airfield and were not able to depress their guns enough.

We cannot model these facts in SPMBT.

Perhaps i will add offmap arty with same weapons as AC-130, this might be the way to model the high-altitude invulnerability of the Gunships well.
