MS-V Veil — Multispectral Obscurant Grenade

Hand-thrown · Pin-pull · VIS + NIR + MWIR · Squad / site magazine

MS-V is a multispectral obscurant concept that generates a dense visual + infrared cloud to degrade fused FPV/thermal UAS observation when paired with standard visual smoke. Employed as 2–3 MS-V + visual smoke. Not a standalone smoke replacement.
