Man portable weapons include integrated electronics that calculate orientation and movement in addition to providing that data to a user's heads-up displays (HUD) as well as to group and area networks. By passing data to a HUD, the user is able to see, virtually, the flight path, point of impact and other ballistic data as well as data representing the condition and performance of the weapon for any rounds fired. The HUD also displays the relative position of other members of the team, last known enemy area of operation and other useful parameters from the man portable weapons of the other team members through the network. The electronics may be integrated within the main components of any suitable man portable weapon in a non-intrusive way as to have no effect on the firing mechanism of the small arm when it is fully assembled.
