DIRECT FIRE CONTROL WITH THE RANGING MACHINE GUN. AN ANALYSIS OF THE ERRORS INVOLVED

Abstract

An analysis is made of the errors affecting the use of the ranging machine gun (RMG) system of direct fire control and an examination of their effect on the chance of hit of the 105 mm tank gun carried out. It is concluded that when used with the APDS projectile the RMG and coincidence range-finder do not offer much advantage one over the other but both show an increase of 20 - 30 per cent in first round chance of hit compared with that given by visual range- finding. It is also shown that with the HESH projectile, the RMG provides considerable improvement in first round chance of hit over visual range-finding, and gives a general increase of about 20 per cent over that obtained using a coincidence range-finder.
