For those visiting in the future…
From my pile of notes ("Misc. DCS Issues and Workaround). This is a partial list (what I could find right away) compiled over the last 2-3 years while trying to get the JTAC/FAC-A to do stuff I could count on. Some of it may be incorrect or corrected by now. In no particular order
AFAC Stuff omitted here
- Built-in audio for IR Mav’s seem to be missing; for weapons you hear, “…use _____” - the weapon type is blank.
- Don’t seem to use MK-80 series bombs.
- The frequency must be on COMM2, not 1, for normal freqs 133.0 etc: Not sure this is accurate anymore
FAC/JTAC Designate Range Criteria
WP-Laser(?) 8NM Think this means Laser-guided WP rockets?
Ground-based JTAC: Laser designation max 3NM.
You can assign the task to the JTAC anytime but the above designations won’t be used until the JTAC is within the given range, ie; an AFAC can be assigned to attack a group anywhere but if you contact them when they are outside those ranges you will get a “Type 3” and “No Mark” - cus they can’t see the target yet (or you I imagine).
Not sure if they ever change the designation, after the first call with “No Mark”, once they do get within range. Even if they do you’d need to communicate this to the player - they would have to RTFM. Best practice is to wait until the JTAC is within designation range then tell them to “contact JTAC frequency 123.4”
Weapons Request Criteria
- Since 2.8, JTACs can now name AGM-65E and AGM-65F (e.g. “request AGM-65E”).
- Devs told me that JTACs are programmed to ask for cannon when the target is “soft” (truck , light tank). Example: if you target a T-72, JTAC will ask for GBUs. If you target a truck, JTACs will ask for cannon (unless your ammo is depleted). This is expected behavior.
- I’ve found that the above is true IF you are packing MK-8x’s. With Mk-20 Rockeyes he will ask for them with soft targets. Obviously not tested very possib
- An issue is yet to be solved: when an aircraft carries a gunpod, JTACs answer “request [nothing]” (reported in another thread).
From the Net:
"What Type of 9-line is it
• unit with line of sight - type 2 in effect (can lase)
• unit without line of sight - type 3 in effect (no mark)
in certain circumstances i.e. looking through a fence, the JTAC can see the Target but not lase it."
The JTAC will only fire the laser for 5 minutes, so you should call laser ON just prior to dropping your GBU-12.
Thanks, AFAIK in DCS this translates to
Type 2: Individual Attacks, the designated target marked by smoke, laser or pointer
Type 3: A location co-ordinate and general area to engage
Which type a DCS JTAC uses is determined by line of sight, rather than the number of enemy units.
The ground JTAC unit has many problems. No mark means it does not have clear line of sight or is out of range.
Its better to use UAV as JTAC. It will find the targets and lase them.
ABORT, ABORT, ABORT
DCS JTAC doesn’t always give you an ‘arc’ for inbound heading. Seems the FAC-A does but the JTAC does not. JTAC will say “Egress north/south/east/west” and it appears they still require the reciprocal of ‘east’. It seems to take into consideration magnetic variation but then, not sure.
