But GR9 has different equipment and does different thing. One example of this is the outrigger pylons/ stations. In the USMC AV-8B is wired yet never used. Even if the USMC AB-8B N/A from different year will have different capabilities since they went through so many update/upgrades. Even flying from Afghanistan or Iraq they are only caring single GBU.
I think the 1A-AV8BB-TAC-050 (NWP 3-22.5-AV8B, Vol. II) from 1998 we can find is 8 to 10 years outdated in relation to the DCS versions, but it matches photos and videos of USMC deployments. When this manual was used, I don't think the Night attack AV-8B could carry the TGP. If we can find a newer NATOPS, that would be great.
