I remember a while back someone wrote a post saying that the AI had to be at certain altitudes to drop A-G weapons. I couldn't find the original post but did find this, which lists the altitudes.
// Change AI A/G attack altitudes
// for instance:
set g_fA2GHarmAlt 20000.0
set g_fA2GAGMAlt 7000.0
set g_fA2GGBUAlt 15000.0
set g_fA2GDumbHDAlt 1500.0
set g_fA2GClusterAlt 5000.0
set g_fA2GDumbLDAlt 20000.0
set g_fA2GGunRocketAlt 3500.0
set g_fA2GCameraAlt 12000.0
Note: in AF AI wingmen seem to use different fixed Altitudes for different bombs types, despite the
F. i. for Low Drag Dumb Bombs, they descend/climb always to an altitude of 15K feets, no matter what set in waypoint alt and which is the actual alt when ATTACK TARGETS or WEAPONS FREE commands are issued.
If for any reason they cannot reach the default altitude, they simply do'nt drop.
This explains the mistery of AI wingmen sometimes not dropping.
See also my post "AI Alt to drop AG weapons" on the subject.
Now, I have no idea whether this is true or not, and it also was dealing with Allied Force. I'm not sure what version you are inquiring about.
And also, the OCA commands are for attacking Airbases. So unless there was a TV station at an airbase, then you may have been using this command the wrong way.
