Which unit of the crime lab specializes in ballistic testing?

The Firearms Unit is dedicated to ballistic testing, which involves analyzing firearms, bullets, and cartridge cases to determine their characteristics and potential links to specific incidents or suspects. This unit employs various techniques, such as microscopy, to examine the striations on bullets and match them to specific guns, as well as testing the functionality and maintenance of firearms used in crimes.

In contrast, the DNA Unit focuses on genetic material analysis to identify individuals. The Explosive Unit specializes in analyzing explosive devices and materials, often related to bombings or other explosive-related crimes. The Chemistry Unit typically deals with substances such as drugs, poisons, and other chemical compounds, but not specifically with firearms or ballistic testing.
