During WWI, slamfire technique were used by US Armies and proven to be effective in trench raid. By doing these technique, operator could unleash rapid fire with devastating effect in less than 2 seconds. While slamfire itself considered extremely dangerous as it would increase a chance of out-of-battery detonation that led into breech explosion[2], The M1897 could be a first shotgun in the world that able --if not, intended-- to do slamfire due the lack of trigger disconnector where it can be fired without releasing the trigger.[3]
The German forces in WWI protested the usage of M1897 Shotgun, as the weapon itself violate 1903 Hague Convention of Land Warfare by unleashing gruesome effect from the shell at effective range and considered inhumane, where using weapon that caused unnecessary suffering to the victim is strictly forbidden. Shortly after German protest was rejected by the US in 1918, German forces issued order to threat US by executing the caught opponent armed with a trench gun or even only with trench gun shells without equipped it. Ironically; flamethrower(2-man Grossflammenwerfer and man-portable Kleinflammenwerfer M.16) and mustard gas that proved inhumane against war convention were originated from German are still used in the war. Even so, there's no record and report of trench-gun armed soldier execution.[4]
General Pershing also counter-threat German forces to execute captured soldier with flamethrower and saw-back bayonet(Kurzes Seitengewehr) due the exceptional injuries that led to painful death to the victims when hit.
The M1897 T-Doll seems to carry the Trench Grade Model 1897[5]
Her outfit is symbolic for "cleaning" (apron, gloves, cleaning agent) the trenches (entrenching tool, trench grade gun), making a pun of her weapon nickname "Trench Broom" aside of Thompson with a same nickname.
