The M1918 Trench Knife is a trench knife/melee weapon.
Call of Duty Online 2[]
The M1918 Trench Knife appears in RisingSun2013's game, Call of Duty Online 2, as a Melee weapon. It acts like the Combat Knife from previous Call of Duties, being a high-damaging, mobile melee weapon that can be held rather than having to be brought out every time the player wants to use it. It is generally a one-hit kill to normal enemies, unless they have 200 health or more. It can be used as a Primary or Secondary; using it as one or both will give the player an extra perk point.
Before an update, it used the long stabbing animation like in Call of Duty: Ghosts, but after an update it now always uses a slashing animation similar to that of the Combat Knife in Call of Duty: Advanced Warfare.
