Description

I dont know whether this was intended, overlooked, or simply just broke. But you cant adjust the range of the M3 MAAWS launcher, like you can do with the M136 or the LAW.

Why should it? You have an optic with shooting marks, correct?

Updated by Iron_Wardog over 4 years ago

Correct, it works perfectly.

Updated by stagler over 4 years ago

Yes it has ranging marks, shame they arent correct. Go and try it.

The range marks work for the FFV 751 HEAT round.

If you have any documentation for the operation of the MAAWS that says otherwise, that'd be a great help.

Updated by Lazyman over 4 years ago

Currently, the way the feedback is worded, there is nothing wrong with the M3.
Maybe what you meant is that the ranging marks cannot be used to calculate the range to a target like you can with either the M72 LAW or the RPG-29?
Also, just like the M3, the M72 cannot be "zeroed" like the AT-4 or the RPG-7.

From FAS.org;
There is a Picatinny Fire Control Device (PFCD) developed at Picatinny for the MAAWS. The PFCD is used as a mount for optical/night sights. It is used to address trajectory differences between HEAT, HE, and HEDP rounds. The PFCD contains a dual function knob that can be used to select round type and range. The original FCD from Bofors was a two-cam design (HEAT & HE). A second knob with a third cam for the HEDP firing. Idea of switching knobs was not favorable by the Rangers, therefore Picatinny was tasked to design a three-cam FCD to replace the Bofors' FCD.

On the Swedish CG the knob below the sight == ranging knob

I've got the swedish army manual for the CG from Nordin on BIF, and it gives an idea of the basics of how the sight system works, but I've been unable to find anything at all about that PFCD thing.

The PFCD is used on the 84 mm Carl Gustaf Recoilless Rifle and is a mechanical device that utilizes four internal rotating cams each of which is matched to the ballistic trajectory of one 84 mm round. The cams are rotated using an external range knob graduated in 50 meter increments. The PFCD is a government owned technical data package (TDP), distribution statement “A”, and will be provided to interested parties requesting the TDP in response to this announcement and who are registered in the Central Contractor Register (CCR).

Dont know if it helps..

That doesn't really say much beyond "there's also an FCD for the MAAWS, which allows you to aim."

In any case, from what I understand of the manual, the original FCD works like this:

  • You aim through a scope. This scope has range marks from 100 to 500m plus a chevron mark on top. We have this in-game.
  • There's a knob, marked HE/Smoke, that has x ticks at x metre intervals (don't know, didn't see it in the manual)
    • When firing with HE or Smoke, the knob is set to the desired range to target, and you aim with the chevron.
    • When firing other rounds, including HEAT (M/66 and M/75 in the manual, I think this is single-stage single-warhead rounds. Not sure how it would behave with the -751, or if the swedish army even uses rocket assisted rounds), the range knob is set to 0 and the range marks on the reticle used to aim.

I'm still assuming the PFCD works similarly, but I still don't know how exactly or which rounds/ranges it's used for.
Maybe it goes 0(HEAT) <-> HE 50m <-> HE 100m <-> etc <-> HEDP 50m <-> HEDP 100m and so on.

Also aren't the horizontal lines supposed to be spaced as a V instead of the current pyramidal form to help gauge the target range?
Currently the sight goes (very) aprox. like this:

|
---------[ + ]---------- 100
I
-------[ + ]-------- 200
I
----[ + ]----- 300

Shouldn't it look like aprox. like this instead?

|
----[ + ]----- 100
I
-------[ + ]-------- 200
I
---------[ + ]---------- 300

Basically working like the M72 sights or the ACOG sights on the rifle when ranging a human enemy.

No, the reticle is relatively correct.
The increasing distance between the lines is for compensating for the speed of the target, not rangefinding.

Oh I see. I never thought the reticle was designed to apply the proper lead to a moving target. I usually just eyeballed it based on previous experiences. :p

I've no idea if it's accurate in game :D

Updated by q1184 over 4 years ago

Attaching the Canadian manual for CG, to add to the information pool. Don't have time to look into it closely atm, but it seems at least the Canadian version has an adjustable sight with a knob graduated for different rounds, as opposed to the ballistic reticle we have now.

Updated by mr.g-c over 4 years ago

It was also my information that the sights have ranging knobs to compensate for the different Rounds.
Should be added if possible :-)

Updated by VKing over 4 years ago

I've done some tinkering on this. I'll look at trying to implement something after 1.6 stable is out.

  • Target version set to 395

Updated by q1184 over 4 years ago

  • Target version changed from 395 to 1.7
  • % Done changed from 0 to 100

Implemented sight adjustment for all ammo types and a new reticle.

RPG-7 also got adjustments that work for all rocket types (recent RPG-7 models have complex ironsights that allow that, can be seen here: http://content.foto.mail.ru/mail/photoshooter/1279/s-1286.jpg).
