The M256A1 Chemical Agent Detector Trainer Kit is designed to train users in the use of the M256A1 field kit.

Trainees use the included 36 sampler-detectors for simulating blood, blister, or nerve agents.

There are five types of sampler-detectors included:

• Twelve (12) that simulate "all clear" responses
• Six (6) simulate nerve agents (G or V) responses
• Six (6) simulate mustard (H) blister agent responses
• Six (6) simulate phosgene oxime (CX) blister agent responses
• Six (6) simulate hydrogen cyanide (AC) or cyanogen chloride (CK) responses
