  1. Hi guys, I'm making a ballistics calculator for vanilla A3 and I'd like to use it to calculate holdovers for the RCO (ARCO, ERCO, MRCO, etc.) family of scopes on a variety of different guns. Essentially, each RCO-style optic has a fixed 300m zero and a BDC reticle with holdovers calibrated for a specific gun (RCO on the MX, ERCO on the SPAR, etc). Common knowledge among the community is that the RCO/ARCO are meant for 6.5mm, ARCO for 5.56mm, etc., but this is not broadly the case. In order to calculate these holds on each weapon, I need to know the reticle subtensions in MOA/mils for the RCO, ARCO, and so on (see this example). I've tried to determine these via experimentation in-game but have only gotten a rough idea. Does anyone have any ideas for how to determine these?

  3. This is mainly for the developers or anyone who actually knows for fact the inner workings of arma physics.... Which model is arma using for calculating ballistic calculations for bullet flight? ASM or ICAO? I see people making mods trying to give 'realism' and they using apparently two different standards according to the ammo data given.Vanilla says ICAO (g7) but also ASM (G1) I just want to make sure that arma can tell the difference.

    Rifleman's Rule

    I have a question on the concept of Rifleman's Rule. Simply, it has to do with aiming lower when shooting uphill or downhill: https://en.wikipedia.org/wiki/Rifleman's_rule Would this apply to other projectiles like rockets and missiles? From what I understand, Arma has a decent ballistics system (obviously with ACE it is even better).

    Scopes zeroing

    Hello I wasnt able to find answer for my questions in any post that I check so I decided to make my own. I need to know : HOW DOES SCOPE ZEROING WORKING IN ARMA 3. HOW DOES GAME CALCULATE WHAT ANGLE corresponds to for instance 2000m zeroing for given weapon? My wild shot is that there is an algorithm that is calculating what angle needs to be set to hit target at 2000m range and 0.0 elevation it uses same function which simulates bullet trajectory. Am I missing sth?
  6. Hello friends, This is Dagger Weapons (and ballistics) for Arma 3. You can download it here: Armaholic: http://www.armaholic.com/page.php?id=30170 Steam Workshop: http://steamcommunity.com/sharedfiles/filedetails/?id=639464956 Six Updater: http://withsix.com/p/arma-3/mods/BwbgUy_jqEipuxRIarFMRg/Dagger-Weapons-for-Arma-3-%28and-ACE-3%29 It adds many new sniper rifles and a wide variety of ammo types, wich use ACE 3 Advanced Ballistics parameters. All ballistics data is based on real life coeficients and you can play the game using your real life ballistics calculator, as well as the ACE 3 ballistics hand held and rangecards. The rifles are based on the wonderful Bohemia´s sample models for Arma 2 and come with many added features like iron sights, rails, etc, and they are painted in many different realistic official camouflage patterns. There are also some hand painted rifles, made using sniper´s real life techniques. Manual, and signature included. No more LEA config file because people use Virtual Armoury now. I hope you enjoy playing Dagger Weapons & Ballistics just like I´ve enjoyed making it. Cheers! photo hosting Requirements ACE 3: http://www.armaholic.com/page.php?id=28557 CBA: http://www.armaholic.com/page.php?id=18767 Extra Notes There are optional configs allowing to use Dagger magazines with Massi weapons, SMA and the 3 RHS´s. BC´s come from Bryan Litz books and they were all set to G1 for the sake of comparison with other calibers with less info on them. Current Version V4. Invitation To My Fellow Moders Hey guys, if you make weapon mods and would like to add my ammo and magazines to your mods it would be an honor for me. Please, contact me so that we can advance this idea together! Special Thanks BI team, for the wonderful game, forums and sample models. Massi, for the iron sights. ACE team, for the the many sniper toys (like the Kestrel, Vec-21, tripod, etc). WG6, for the M24A2 idea. AR15 and Sniperhide forums, for the open minded discussions and mutual help.

V2: Added bump maps and specular maps to the weapons, added new ammo types, improved the weapons 3D models. V3: Synced with Steam Workshop. V4: Shared a sudy on Arma 3 ballistics, revised the penetration and damage system, fixed some .308 BC´s, made the ammo SMA, RHS and Marksmen DLC compatible and removed the message at the startup, fixed some rifle dispersions, added different shot sounds, added HP ammo to .300 blackout and 6.8 SPC calibers, fixed assault rifles magazine muzzle velocities to match ACE rifle barrel length parameters. Reduced weapons mass to allow carrying them inside backpacks with other stuff.
  7. I created a ballistic computer (external Excel spreadsheet) for artillery. The difference between what I created and what I have seen elsewhere is that I added a calibration function. The concept is that you provide the initial inputs and fire the first round, then input the coordinates of where that round impacts, and the sheet automatically updates the yellow cells for the adjusted bearing and elevation. This calibration is valid as long as you consider the following assumptions: 1. As you drive the vehicle, any change in position AND/OR change in elevation will throw off your calibration by the same amount. 2. The calibration value is most accurate at the bearing you used during the calibration process, and your results deviate more as your turret deviates from that initial bearing (if you target something 90° from the original target, don't get mad when it's not accurate). All of the testing was completed using the M4 Scorcher, however the M5 MLRS and the MK6 Mortar is included in the file. The equations don't change, only the muzzle velocity values, so if there is any issue with the results start by verifying the velocity values. Using the M4 Scorcher, I drove to a distance of 5.6km, entered my cords and the cords of the target, fired the first round, entered the impact cords, and put rounds on target consistently after that. Remember, the performance of the computer is dependent on the accuracy of the data entry. Calibration process: NOTE: ONLY CHANGE VALUES IN THE GREEN CELLS. 1. Enter your vehicle type in cell B6. 2. Enter your cords in cells B7:B9, using the 4-digit format. 3. Enter the target cords in cells B10:B12. 4. Adjust your firing mode according to the value shown in cell B17. 5. Adjust your bearing according to the value shown in cell B18. 6. Select an elevation value to use for your calibration shot; in theory the "high" value will result in a more accurate calibration (this isn't real life btw), although in practice the difference seems small. Fire your calibration shot. 7. Determine the impact cords of the calibration shot, either by watching the map (King of the Hill) or by utilizing a forward observer. 8. Enter the impact cords of the calibration shot as follows: a. If you fired the calibration shot using the "high" elevation value, enter the impact cords into cells E10:E12. b. If you fired the calibration shot using the "low" elevation value, enter the impact cords into cells F10:F12. 9. The calibrated bearing and elevation values automatically populate into the yellow cells B18:B20. Adjust your turret to the corrected bearing and elevation values and fire at will. Notes: -Re-calibrate any time the vehicle is moved, or if you change target cords and the bearing changes changes more than a couple degrees. -If you can't get the system to work and you are following the steps above, verify that you are in the correct firing mode by pointing at something far away and cycling firing mode until you locate the short range mode, then cycle forward from there. -The computer is set up such that: -You can keep the same calibration values in E10:F12 and change to different targets in cells B10:B12 without affecting the calibration. Remember the assumptions listed above when doing this. -You must clear all of the contents in cells E10:F12 before you can accurately RE-calibrate your firing. (Actually clearing the contents from cells E10 and F10 will remove the calibration effect from the yellow cells, if you are in a hurry). -The computer will return an error message if there are values present in BOTH cells E10 and F10 at the same time.
