Buddy lasing with BRM90

Quick question, I was trying to do Buddy Lasing.

I was in the JF-17, and an F18 was lasing in the 1688 Laser code. Couldn't do Buddy Lasing.

Any thing I'm doing wrong?

They are currently using a beam-riding guidance like the Vikhr (as a placeholder), and that means they can't be buddy-lased. Unless maybe the guy lasing is flying right next to you as you fire, haven't tried.

No, BRM doesn't uses beam riding anymore.

Now the rocket doesn't spin and I think it's using the AGM-65E scheme.

It doesn’t work if your rockets are on 1688? You have TGP? Don’t you have to set laser code on the ground or is 1688 by default for Jeff?

Oh, I'm behind the times then. Thanks for setting that straight and apologies for spreading misinformation.

Doesn't explain why the OP can't buddylase though.

It shows for defaultin 1688 at least in the Weapons page. I did it with an Airspawn, maybe there is a bug with airspawn

It shows ? you mean it works?

Im genuinely curious now u brought it up

thatd be VERY useful; especially say with a JTAC

Pretty sure that’s your problem. I think the weapon page changes the laser code of the TGP laser, and that the weapon laser code has to be changed on ground via ground crew

Did you work out what the issue was? I haven't had a chance to try it myself yet but I'm curious if it works.

What comes considering the APKWS II (coming to A-10C, Kiowa Warrior at least) it has the laser code set by the ground crew before inserting rocket to the launcher.

But DCS is known to fake these things by adding unrealistic capability to change weapon laser code on all weapons than just the ones that would allow it with a digital connection.

So, how it is suppose to be set in BRM90? Is there a digital connection between FCS to the rocket set it before launch, or is it just faked as well to make players lives easier?

Th JF-17 cannot set weapon laser codes from the cockpit. So it is not faked. Weapon code is set on the ground per pylon (so all rockets in one launcher will have same code). In cockpit you just set the code the laser transmits, to match your weapon setting or for someone else if you need to.

Negative, couldn't found a fix :(

Just tried it, can confirm it doesn't work regardless of using default 1688 laser code or something else.

Another weird thing: self-lasing, the BRMs track regardless of whether the TPOD code matches theirs or not. Seems the guidance is still placeholder or hard-coded in some way.

Actually, buddy lasing does not work at all with JF-17 as the "receiver". My GBUs did not track an F-18 lasing, but his GBUs tracked my laser.

Laser Search works fine and tracks, so I don't think we were doing anything wrong in testing.

That is nice to hear that it is done properly in JF-17.

Is it done using kneeboard?

Correctly then. Last time I tested it, it was air started and worked properly right away with default laser code.

No, it's done in the Ground Crew radio menu.

That's because the default laser code for everything is 1688, so everything will work, but with that laser code

Tested again in Single Player with JTAC.

Laser Spot Search (LSS) works

GBU-12 buddy lasing works

BRM buddy lasing does not work.

BRM will not show IN RNG icon, or allow any launch at all, unless the TPOD is pointing inside the aiming circle.

And, further to my point above, the BRM guidance is hard coded:

It doesn't matter what laser code the TPOD is on, or even if the laser is not firing (set to MAN and left off), the BRMs will track where the TPOD is pointing no matter what. It will ignore other lasers, even lasing on same code directly in front of it.

Hopefully the AGR-20 scheme, once implemented will fix this issue

Yes, hopefully, but there are already schemes that should work.

Someone said it uses AGM-65E, that can be buddy-lased fine. So either it's not using that or it's broken/incomplete.

There are also Russian missiles (S-25L I think?), not sure if that can be buddy-lased. Maybe that's the scheme it's using, since it's a Su-25T only missile (FC3 level) it might be why it feels "simplified" in the JF-17 too?

S25-L can be buddy lased on code 1113. But I don't know the answer for the other questions

now it's S-25L style rocket which has no scheme. so some advanced API for scheme based weapons are not usable. Will check with ED and see whether there's solution instead of changing to akpws scheme

Thank you for the update uboats. Howcome the AGM-65E scheme can't be used?

For the meantime, I will try to test if BRM-90 can be buddy lased on 1113 like paco says S-25L can be.

So...

I wouldn't waste your time trying to do this until the APKWS scheme comes in this won't work or buddy lasing in general with brm's, I checked this the other day with a friend we tried with a KA50 and 25T and we found the brm's have the current restrictions

1) you need a TGP loaded and ground stabilised in area mode for them to fire

2) BRM's do not seem to use any form of laser they will hit where ever the TGP is looking in area mode whether it's lasing or not (you can check this by turning auto to man lasing on the TGP)

3) they will not follow an external laser source

4) they seem to be behaving more like saclos missiles rather than laser guided missiles right now

Yes, this is exactly what I found in my earlier testing as well. But I was just going off what paco said, if S-25L can be buddy lased on 1113, maybe just on that frequency the BRMs will accept it too.

That was my thought process for the above all the russian L series apparently use the same seeker however the laser code second digit can't go below 5 on the airframe so not possible (check in the ME aircraft options) which is why i thought to try the 50 and the 25t with a friend because it is possible for the ka to buddy a 25l for a 25t but it's fiddly.

But yeah see my post the brm's are behaving like saclos missiles right now they'll track where the tgp is looking with a laser or not and won't see any external source - definitely better to wait until the apkws code gets attached to them, the current scheme is literally just a placeholder but it works so meh.
