Firstly I would like to say I was quite impressed with the work WT did on the AVRE, i began to read with some trepidation but found to my surprise that a lot of the information and statistics was within the sort of boundaries one would expect without nit-picking.
I was particularly glad of the correct tube calibre being added at 230 mm, seems my video did its job with quite a few reposts on various places, the 290mm myth is finally coming to an end.
I did however have a good rummage though the archive files for the range and testing of the 29mm petard to compare it.
The muzzle velocity of the round was: 172 ft/sec
Weight of shot 40lb
Filler 26lb
Effective range 75 yards - Note at 50 yards the accuracy was off by up to 4ft!
Maximum range 234 yards
So the only real difference is the guns maximum range is off however it seems to have much better dispersion than the real one. which to be fair was made to punch though a mile long concrete wall, hard to miss that.
The only other issue was the AVRE as seen in the game, a late model had armoured ammunition bins as did all late models retroactively. I’m not sure if those have been added. also a smoke round was made if Gaijin wanted to add a really big smoke bomb.
