Hilts Posted October 26, 2017 Share Posted October 26, 2017 Got a situation where I have some T34/85s and some JS2 tanks. I just noticed that the T34 off road capability is only 3 yellow bars whereas the JS2 has 4 green bars! Can this be right? I always thought the T34 was legendary for being one of the best off road tanks in existence at the time and would have thought that the heavy JS 2 was much more likely to bog. 0 Quote Link to comment Share on other sites More sharing options...
MikeyD Posted October 26, 2017 Share Posted October 26, 2017 There's no telling what exactly the 'bars' are detailing. T34 and IS-2 are pretty close on ground pressure with just one pound difference. T34 was 10.5 psi and IS-2 was 11.5 (VVSS Sherman was 13.7psi). IS2 has the more powerful engine at 600 hp, T34 was 500 hp but still bested the IS2 by 6 horsepower-per-ton at 18.9. T34 tracks were 500mm wide, IS-2 tracks were 650 wide. Perhaps Charles is biased against the bell-crank Christie flat track suspension, prefers torsion bas suspension with return rollers. 0 Quote Link to comment Share on other sites More sharing options...

Maybe that's it because 3 yellow bars is only one bar better than a Soviet truck although according to the manual the T34/76 and the T34 flame tank both have 5 green bars! I have a feeling though that are going to be some angry folks on here when we start playing in the mud and the snow and all their T34/85s have bogged down. 0 Quote Link to comment Share on other sites More sharing options...
Chibot Mk IX Posted October 27, 2017 Share Posted October 27, 2017 T-34/85’s off-road capacity was not so great compare to T-34/76. The new turret changed the center of gravity, it also made some part the suspension system reach the overweight limit. 0 Quote Link to comment Share on other sites More sharing options...

Thanks for the info. 0 Quote Link to comment Share on other sites More sharing options...
Sgt.Squarehead Posted October 28, 2017 Share Posted October 28, 2017 (edited) Been consulting 'The Bible', so far the most pertinent info I've found is a ground pressure for the T-34/76 of 0.62kg/cm2 with 550mm tracks or 0.7kg/cm2 with 500mm tracks. This increased to 0.85kg/cm2 with the T-34/85 with 500mm tracks. To put these figures in perspective the M4 Sherman is quoted at 1.1kg/cm2, the Pz.IV E-F at 0.88-0.91kg/cm2. An interesting related quote: Quote For a tank type such as the T-34, the maximised ground pressure values that were reached in 1941 were simply overkill and it was possible to easily sacrifice them partially for the sake of a thicker armour, better armament and other unnecessary design features Not sure the last bit made it through translation unscathed, but it seems to me that only the earliest production T-34/76s (m.1940 & m.1941) should have all the green bars.....Things should start to go downhill (relatively speaking) with (IIRC) the T-34/76 M.1942, then take another dive with the T-34/85. PS - Still looking into the situation with the suspension, the tank's weight certainly took a jump.

Sgt Joch Posted November 10, 2017 Share Posted November 10, 2017 many factors go into a AFV's off road capability, i.e. ground pressure, suspension design, MMP rating, durability of components, etc. The game does not rely on any one factor. the Bar rating is only a rough indication of off-road capability. I had run some bogging tests of the T34-85 (3 bar) vs Tiger I (4 bar) some times back and in game performance of both was very similar: Quote So I ran some more tests. 4 km long map, mud, cool temp, damp ground, overcast. 10 AFV each run, 5 run. 1st test: T34-85 (1944 late) -17 made it to the end -33 immobilized -total distance travelled: 122,707 meters -average per tank: 2,454.14 meters 2nd test: Tiger I late -17 ok -33 immo -total distance travelled: 125,394 meters -avg per tank: 2,507.88 meters So results are basically the same. 0 Quote Link to comment Share on other sites More sharing options...
