4) Gunshot Residue Distance Determination – creating and analyzing test specimens to illustrate the approximate distance a firearm was discharged from an individual. This test can produce crucial evidence when assessing the validity of witness statements.

5) Operability and Microscopic Report Review and Evaluation – professional review of case notes, case files and scientific reports relating to firearms operability and conclusions based on microscopic examination.
