Russian OOB -

[Shan]

I found some inconsistencies concerning the rate of fire of self-propelled mortars:

Russian OOB: Units 593 (2S9 Nona), 594 (2S31 Vena) and 595 (2S23 Nona-SVK) alle have a ROF of 5 (just like conventional 120mm SP mortars).

Ukrainian OOB: Units 593 (2S9 Anona) and 595 (2S23 Nona-SVK) both feature a ROF of 7 - now, I don't have any proof but I suspect these are exactly the same units and therefore should have the same (higher) ROF due to the advanced loaders.

Absolutely with you it agree. Also it is not clear why it of the weapon refers to SP Mortar. It not so. It SP Artillery or Light SP Artillery.

Here links to a factory which lets releases this weapon:

For Nona-S, SVK, Vean - special shells have been created, but it also can shoot and mines for Mortars. The weapon has been created specially that it was possible to use shells of the probable opponent.

ROF in the unit stats screen is a bit of a deceptive stat as it has little direct effect on the actual ROF of units in the game. Experience of the unit has a lot more effect. Just try it out by changing the ROF of units and see what difference it makes in an actual set-up and then vary the experience instead and see what difference that makes.

This difference in stats is extremely minor in it's actual effects on gameplay and most often it will have none at all. Still, it will probably be looked at some time int he future but in the mean time, don't worry about ROF scores.

PS do a search on the forum for other ROF related threads for more details on this.

Ok. Whether will be my very skilled units, for example Exp. = 100, to shoot more than ROF=5??? No.

Moment here. As far as indirect fire is concerned, I think ROF has a direct influence on the number of rounds shot per turn on a fire mission. Since all the units mentioned above are generally classed as SP mortars or similar, it should be of some importance.

Now I don't know exactly how much ROF means how many RPM, and which level of actual ROF is to be considered (i.e. instant, burst, sustained).
Better chack with comparable artillery units.

My main point is that identical weapons in different OOBs should have the same stats. I didn't really want to start a ROF discussion but anyway -

To PK and the others: ROF matters - fully agreed - and I did check: the average 120mm mortar carrier has a ROF of 5 and it also shoots 5 rounds in a salvo - whereas the heavier ones (160mm) have ROF 3 and 240mm Tulpan has ROF 2.
My experience is that ROF is the main factor in the buying decision - the larger caliber makes 120mm mortars more effective but you'll neve achieve a fire density as with 82mm - and very often, never even hit your target at all if you have no spotter. And if you check the other advanced breech-loading SP mortars in the game (only single-barrel versions though) then you'll notice they mostly have a higher ROF than 5, some up to 9, as far as I remember (I dont have the game on this PC for reference).

No it isn't. Just try it. I just set up a test game for 2005. I bought some 120mm SP mortars GAZ-3937(listed ROF 9), 2S3S Nona SVK's(ROF 5), 2S31 Vena's (ROF 5), 2S9 Nona S (ROF 5).
Every single one had exactly the same actual rof in the game (3).

Really, the lsited ROF of a unit in the info screen is NOT very relevant. The calibre of the weapon (and warhead size) and crew experience and nr of crew are.

From actual testing:

at experience 120 the GAZ-3937's with ROF 9 all have an actual in game ROF of 5.

at experience 120 the Nona and Vena SP-mortars with ROF 5 all have an actual in game ROF of 5.

at experience 150 the GAZ-3937's all have an actual in game ROF of 9.
And guess what? At experience 150 the Nona's and Vena's have an actual in game ROF of 9.


Save yourselves a lot of time and effort and DON'T BOTHER about differences in the ROF stat. It's not important.

My guess is you've made tests using direct fire, no?

Made an experiment with clones of the same M113GA1/Tampella 120mm with RoF 3, 5, 7 and 9, purchased in groups of 6 each

RoF 3: 3 rounds fire mission fired

RoF 5: 6 rounds fire mission fired

RoF 7: 8 rounds fired

RoF 9: 10 rounds fired

The game deals differently with direct and indirect fire re RoF, in DF mode all the other factors are important, in indirect mode the RoF is dominant as it seems.

Thanks Marek! That's what I was talking about all along, I thought I had made it clear.

ROF value is highly determinant in indirect fire aka artillery missions, not unit-to-unit direct fire. Reversely, experience rating of indirect-firing units don't matter much (experience of FO unit does though).
