REACT UV Light is a Codex featured in Tom Clancy's Rainbow Six Extraction. It is unlocked by default.

INDEX Analvsis: The REACT UV Light is a broad-spectrum portable light source developed by R&D labs for field incursions.
Used by Operators to stimulate bioluminescence and biofluorescence in Archæans.
NOTE: Stimulated light emission is a relatively recent adaptation in Chimera organism. Evidence of behavior was not reported during previous contacts (Cross-Ref: Operation Outbreak).
EXTRAPOLATIONS:
Assessing emergence of bioluminescent behavior: Sample study of photo-reactive Chimera cells reveals genetic similarities to various abyssopelagic species found on Earth (QUERY: deep water organisms/medusozoan + cephalopoda + other?). (INSERT: IQ - Implying recent contact? If Chimera is propagating by sea... We have a big problem. Thinking of deep-drilling oil platforms.)
Speculating on rate of adaptation: Recent development of photo-reactive cells supports evidence of rapid evolutionary capabilities of Chimera organism. Requires more data.
PROTOCOL:
REACT UV Light enables detection of Archaan variants through obstructions, and detection of structural Weak Points in environment (Cross-Ref: Analvsis of Chimeran permeation /infrastructure). Net tactical advantage - High.
Enables detection of Archæan Weak Points (kill zones) and armored areas (carapace) on variants. Net engagement advantage - High.
