Sgt. Nathan Stahl, section chief, Battery T, 2nd Battalion, 10th Marine Regiment, 2nd Marine Division, II Marine Expeditionary Force, receives a fire mission from the fire direction center during a field exercise here Dec. 19. The M777A2 Lightweight 155mm Howitzer cannon, aka –triple seven,” brings a new set of capabilities that the formerly used M198 Medium Howitzer cannon did not have, such as a digitally controlled fire system and a VHF radio link that sends command messages to the gun’s section chief.
