The GAU-19 is supposed to spew around 1000 rounds of party mix a minute
at a target, although the normal ammo load would be about 500 rds,
although the initial claims of GenDynamics that the would be less
maintenance intensive has turned out to be false. You can't be
any less maintenance intensive than a Ma Deuce. Fielding should
commence this year
Now if you really want to model an OIF -58D in all of its bad@ss glory,
have the co-pilot engaging Al-Qaida out the left seat with his/her
M-4. I've heard many a "winchester" call and then hear, "...
engaging with my M-4" in support of the boots. That would be a
diorama worth admiring.
The Cav have teamed up with, ahem, the Apache knuckledraggers and
reformed the pink teams. No standard loadouts from what I've seen
but the normal is .50cal/7shot or 2 x 7 shots.
