way out of the norm. They say that the numbers represent US penetration standards. But, I have never found US firing tables for these guns. None that are from testing. Several people have made them from calculations but they aren't true tested values.

Rifle ballistics. I'm taking on rifle ballistics for the German K98k and Russian Mosin-Nagant.
While this has little practical application for Panzer War as the table gets fiddlely at that scale it does work for Panzer Command. As the bullets are used in the light squad machineguns this works for them as well.

Calculations on optics of sights. Why did the British evaluation of light transmission of German TF-5b sight so much less than their evaluation of the Russian TMFD sight?

Wiki is wrong. OK, yeah it often is. But US 76mm M1, M1A1, and M1A1C had 40:1 rifling twist. Only the M1A2 had the 32:1 twist. 3" M5 and M7 also retained the 40:1 twist.
Updated the bomb table of NAAB2.1 with modern bomb GBU-39.

The NAAB2.1 program is changed slightly again. I received an note from Nathan Okun saying that the elongation scaling should be limited to 18". So this has been done. There was another change made as HCWCLCR is updated to HCWCLCR5. Download NAAB 2.1 with bombing here.

The NAAB2.1 program is changed slightly. The diameter scaling is cut off at 20" right now. One other idea may be have max scaling linked to elongation.

I'm just going to cut off the scaling a 16" until I find a better solution. You can download the NAAB 2.1 with bombing here.

Whoops, I'm having a problem with the bombing section. Using HCWCLCR the program fails when the bomb (shell) is too wide and the armor percent elongation is too low. The scaling algorithm goes to hell. Basically, it can multiply the NBL by 0 if the bomb is sufficiently wide as is the Tall Boy and Grand Slam and the percent elongation (PE) is lower than 25%. No problem if the PE is 25% as the scaling algorithm goes to 1.
So here is the problem - the scaling equation.
IF ((PE < 25) AND (D > 8)) THEN NAVYBLM79 = NAVYBLM79 * (1 - (1 - SQRT(PE / 25)) * (D - 8) / 8).
