There must be some kinetic value to an HE round. In a panzer 4 it takes 15 rounds to kill a VH, sitting beside it or 3200 away. have killed m3's and m8's with HE close up, but no luck at long range even thou the hits were similar placement. So there must be some kinetic value that drops off with increasing range. 3 pounds of TNT is 3 pounds near or far.

I think it has done so that there is of course a value for chemical power but it functions as kinetic energy i.e. it drops off at distance.

HE rounds have both an chemical and a kinetic factor, the kinetic factor does less damage the further away the hit is, the chemical factor is constant.

Anyone know how many HE rounds a hanger takes to kill? Seems think i put 20 rounds into one before it finally blew up.

It has to do with kinetic energy.  The equation for kinetic energy = (1/2)*(mass)*(velocty^2).

As you can see, the slower a round gets, due to drag, it loses energy(quickly since it is squared).  I'm certain this is all factored into AH, including drag coefficients and air resistance equations, identical to real life physics equations.  Creating an online environment that mimics real life physics is the first step to creating a flight sim I would assume.

Go to http://trainers.hitechcreations.com
Look for "Projectile Strength Analysis"
You will find the exact values needed to destroy any object in offline mode. Go Options/Arena Settings/Objects/Object settings. All values are given as fractions of 1000lbs.
The tables that can be found on HTC help website as well as the Trainer Corps homepage have the values rounded up.

it depends on the tank being used... if your using a tiger it is less than 15 if your using a T34/76 it is more... with a panzer it is 15...

Ah, got it. I had it to within 4 rds, but I never knew the exact numbers. What is it for the M4A3 (both models if you please)?

I keep on my guns set at very close range. When I am in the B25, I usually have all those set at 400 due to high number of rounds (unless they are  :lol - :lol ones, aka rubber) of hitting the target.
