    "The Firearms Process Map (Current Practice) provides a visual representation of the current methods, procedures, and decision points in forensic investigations of firearms in the United States. The scope of this process map is limited to core processes such as the examination of firearms and the microscopic comparison of fired ammunition components. Individual characteristic databases, toolmark examination, fracture matching, and distance determination are not included in this map. Extensions to this main process map have been developed in an effort dubbed Firearms 2.0:\nIndividual Characteristic Database, https://doi.org/10.18434/mds2-4274;\nSubclass Evaluation, https://doi.org/10.18434/mds2-4275;\nDistance Determination, https://doi.org/10.18434/mds2-4276."
