Which of the following is NOT listed as an odor MWDs are trained on?

• A. TATP
• B. Ammonium nitrate
• C. C-4
• D. Smokeless powder

Answer: (A)

MWD odor sets are built around stable, safe, repeatable scents that reflect common explosive threats the dogs may encounter. TATP is not typically included in that standard training odor set because it is highly unstable and dangerous to produce, handle, and store. The risk and safety concerns make it impractical for regular training using the real compound.

In contrast, ammonium nitrate, C-4, and smokeless powder are standard training odors. They represent common explosive formulations and can be provided in safe, controlled training aids, allowing dogs to learn and discriminate these scents reliably. Some programs may use non-hazardous simulants to mimic peroxide-based explosives, but the actual TATP odor isn’t part of the routine training set.
