Well, that munition is quite owerpowered as it has to have enough energy at a decent distance to deal damage to aerial targets. Thus, it can literally propell itself backwards. Also, that fire-rate has some serious recoil growth effects.
But it shouldnt actually move at all. Have some schematics and the whole thing hasent even any recoil-dampers. Its mostly due to keeping the most acuracy at least for short-fire bursts. Dont think the whole thing would survive two magazines full auto due to the stress it puts on the gun-mounts and theyre mouned directly to the turret basin. (the barrel would need to be scrapped too due to owerheating deformalityes ... know there was a recent thing involving a TunguskaM1 system that needed the moutnts checked after it got bersec by some software fault and barrels replaced before further use (it may be 30mm but its kinda the same white 23mm AA guns) ) And im pretty sure that one gun wasnt really properly mounted (you can see the other fixed just fine and other fire-shots dont have such a laggy gun on others).
Steel-Rat ... I can split up those legs too - some little nivelation tweaking would be possible then (adjusting the platforms stance a little in inclined terrain). Ill try to do all the stuff in the model, but might take till saturday. Also, not sure if i should do collision meshes on the wheels --- as i remember speaking white Cameni, wheels are just in vertical direction. If an animation of putting this thing on its wheels should take plance, im pretty sure id need them to let it stand up properly on them.
