Many Gunners also get their blood types tattooed onto their foreheads by their medics, as this is both a practical measure and a rite of passage. Based on patterns of speech and terminal entries, the Gunners place great emphasis on loyalty and do not tolerate insubordination. The origins of the Gunners and their recruitment techniques are largely unknown although it is known they employ from raiders, who upon joining, may have difficulty adjusting to the strict environment and regimentation of being a Gunner, the only known example being Tessa. The Gunners are lead by Captain Wes, with their headquarters being Gunners Plaza.
They are well-disciplined, highly-equipped soldiers for hire with their own customs and signage, who control numerous strongholds both in and around the Boston area. The Gunners are a paramilitary mercenary organization and are the largest single faction in the Commonwealth, acting independently of any government or settlement.
