Learn the ABCs of ballistics! This online forensic training course introduces the principles of firearms and ballistics!

About this Event

Bullets are as unique as fingerprints. Each bullet, once fired, has characteristic marks (striations) that can be linked back to the gun to which it was fired from. This interactive workshop will provide the basics of ballistics--ammunition, bullets, and casings--and the case studies presented will show the relationship between projectiles and forensic science.

The workshop is being presented by Forensic Training Unlimited, a premier source of online training for forensic students and forensic professionals.

The course is ideal for any student looking for hands-on training from a forensic expert, networking opportunities with other forensic students and forensic professionals, preparing for a forensic career or law enforcement career, or is looking for professional proof (certificate of completion) to show when applying to forensic positions.
