Considering the advent of modern and advanced weaponry and the significance of the needed time for applying these weapons when the country is invaded by enemies, we were committed ourselves to conduct a research military project for automation of 106mm cannon. It must be noted that there were some discrepancies in the conventional cannons for chambering and shooting for which the improving solutions have been investigated in this research so as to take advantage of this crucial defensive weapon in potential wars threatening our nation. This research is intended to automate a weapon called “106mm cannon”. So long as this weapon is manufactured, a large deal of time -currently devoted to chambering (bullet-loading), cartridge-extraction and shooting- will be saved, and all the procedures will be done automatically and more precisely requiring less operators.
