Flintlock is a muzzle-loaded gun, which shot lead balls after gunpowder and ball have tampered into the barrel and another portion of gunpowder loaded into the flash pan. Trained soldiers could make 3 shots per minute; its effective distance is 100 meters.
Initially, it was made manually by craftsmen, and because of this Roland could produce only four flintlocks before Months of Demons has begun. With constructing of more precise Steam Engine II he could start boring of barrels from iron bars, making 10 barrels per day and equipping a hundred of soldiers by the end of winter.
For defence in melee, Roland invented a casing bayonet. The end of the shank had a corner and was connected to a casing. The casing diameter, which was slightly larger than the barrel, was attached to the Z-shape tongue and groove joint. The barrel only needed to be welded with a small iron bar, so that the tongue and groove joint could be embedded in to fix the blade. The blade was a sharp triangular iron cone, its cross-section similar to a V-shape. Such a form did not affect the pulling out, yet leaving a wound that was difficult to heal.
