The government requires a man-portable system for identifying and classifying chemical hazards and quantifying low-level vapor and aerosol hazards, operating in a dismounted configuration worldwide. This system will support missions including post-attack monitoring, base defense, decontamination assurance, demasking, dismounted reconnaissance, and field confirmatory chemical analysis. The effort may result in full rate production and deployment of MPCSAs in tactical environments. No specific timelines, budget amounts, or performance location are mentioned in the description. The government is updating market research to ensure technical and manufacturing readiness information is current.
