Ranging charts for GV sights

[DEECONX]

I remember a good while back someone posted a really great ranging chart for using the Zeiss panzer sights. I found the link for the article explaining how the triangles work, etc etc, but as the article said doing math on the fly while possible being shot at isn't optimal, so having a hand dandy chart nearby helped. I remember getting such a chart, and having it hanging next to me, but can't seem to remember where I got it.

If anyone knows what I'm talking about that would be great.


Also if anyone has something similar for the US and Russian tanks that'd be great as they are trickier to use it seems. The one for the Zeiss makes GVing in them almost a breeze, so long as you spot them first!

Offline the <.target range heading azimuth> is your friend.

Each ring of the target is 10ft wide. Tanks are roughly 10ft x 20ft. I use a thumb marble mouse to aim my main gun with for the fine precision adjustment control.

So offline you can setup in your tank, pull up the target at any range you want to test and keep notes. That is how I built reticle for the wirbel and osti with range marks in them.

If you want to get fancy, take a screen shot of each range through the main gun sight. Then clip that out and put together an art file with each range against the target pasted in along with using the "Text" feature to annotate the range next to it. Then print it out and tape it up over your monitor. Or send it to your smart phone and pull up that picture during your session.

Thanks but someone had a chart with all the work done that was super easy to use like

"X" tank

Mils       length       width   height
1           5,300       2100     2k

Etc etc


If no one has it, I'll end up doing that. thanks

I guess we could pass the hat and pay Skuzzy to whisper in your ear when you are ranging.

I think this is what you were wantin.

Thanks but that's the part I already have. See at the bottom where he has the chart for those tanks? Someone had one just like it for all the AH vehicles. That's what I'm looking for.

I never bothered to make a table; I just do the math mentally.

Here's what I do for the T34-85:

The sight has little caret marks "^" separated by colons ":".  If your target is a Panzer and it is broadside and takes up the distance between two ^, ie ^ : ^ then it is at a range of 800 yds.  So the math is easy.  If it is further away and spans only ^ to : then it's 1600 yds.  If it spans ^ past then next : but only half way further to the following ^, then its 1200 yds.  If it spans ^ : ^ : ^ then it's 400 yds (although I tend not to set the range to less than about 600 because there is a parallax error between the sight and the gun barrel).  If the Panzer is head-on then just half all these ranges (since the Panzer is about 1/2 as wide as it is long).  If the target is a Panther, which is a bit longer than a Panzer, then add a bit of range to what's listed above.

Now how much to lead?  If the Panzer is traveling across your view lead him by two ^, ie ^ : ^ : ^.  If the target is a faster tank, say a T34, then lead a bit more.  If the vehicle is much faster, like an M3, lead almost the entire set of ^.  This presupposes the vehicles are moving at maximum speed; you can judge that visually and make corrections.

Alright! Assuming the measurements from Wiki were correct, and assuming the models in AH are scaled accordingly, the result is this! Spent the morning with a large cup of coffee and some music to give all my fellow tankers who struggle with my math on the fly a handy dandy chart. Tested it a bit in offline on a tiger II at various distances and almost everytime it either got me a first shot hit or a guaranteed second shot.

Hope at least one other person finds this useful.

In AH 1Mil = 2pixel

You do know that range in game is an illusion because of this? There are no fractional pixels. You create gunsight reticles for this game long enough to the AH optical Mil spec, you catch on. You want to vulch the rearm pad from 4931yds with a 410? It all becomes some variation of 4500, 4750 or 5000.

That is why you need to build your charts against the offline target based on pixels which have no fractional illumination. And why range becomes an illusion, so in between whole numbers you guestimate. Or get Dr7 to give you a mind meld.

How far away is a tank that only causes one pixel to illuminate? How far away is it while it drives at you while being represented as only a single pixel? Then how far away is it driving at you the whole time it is represented as two pixels? And so forth.......

The offline target with AH calibrated 10ft wide rings is your friend out to 36,000 yards. At which point it's about 4x4 pixels if your monitor will let you see it.

I rarely use the ground vehicles because I can only hit things point blank. I'm going to try this. What's the unit of measure for the sizes you gave? Thanks for the work. ~S~

According to the article on the 75th 's sight, Mils (those triangles in the german tank sights) are measured in meters, so that's what I used. Combine that article with this chart and you should be able to get rounds on target in 1-2 shots generally.

A little late but I believe this was the charts/info you were referring to.  Not certain though.  You're the one that posted them.     Not sure who you got them from though.

DEE,

Before you get to far into this, here is something Hitech straightened me out on about his game when I went overboard a few years back calculating milliradians.

From Hitech:

1 mil is  1 unit wide at 1000 dist.

I.E. the angle of 1 yard at 1000 yards. Or 1 meter at 1000 meters , or 1 inch at 1000 inches.
--------------------------------------------------------------------------------------------------------

1Mil = 2pixel

If you are going by meters, then a tank is 2pixel wide at 3000m (3281yds). But if you are measuring by 1mil is 1unit at 1000m, and 1 "Hitech" Mil = 2pixels...........illusion in a 2D environment.

HU = Hitech Unit

So again, the offline target is your friend because it's rings are 10 HU in width.

Aha! I knew I wasn't crazy! Thanks Bug! 

Thanks bustr, I'll work with that and see what happens. Luckily only taking a few online classes this summer so time wasn't an issue with this little project. Just trying to improve my experience and maybe someone elses.
