Abstract : Conventional tank battles are an important aspect of current and future warfare techniques. Even though our mechanized weaponry is extremely accurate, we should not embrace the mindset that the beg in tank gun accuracy has been achieved. We can should embrace the mindset that the best in tank gun accuracy has been achieved. We can and should do more! The fleet zero concept brought about by the downsizing trend in today's army means that zeroing exercises will be conducted for the entire fleet using only a few tanks and gun tube. The contribution of individual tubes to a tank's accuracy is no longer determined. Therefore, for the concept to work, variability in tube-to-tube manufacture (or more importantly the variability that ccntributes to accuracy) must be minimized or accounted for through the use of computer simulation. This repofl presents a comprehensive study into the relationship among the characteristics of gun tubes' projectiles, gun mounts' and ballistics and their effect upon dynamics at the muzzle and shot accuracy. The data is provided from the dynamic index tube test conducted in the early 1990s. Modelling is performed using Benet's gun vibration model and a recently purchased gun vibrations code. The overall goal is to provide aiming point correction factors based upon system dynamics and an empirically determined exit jump offset for a specific round and ballistic load. In this type of analysis, the values of uncertain or unknown parameters are randomly drawn from an expected statistical distribution.
