MS-V Veil — Multispectral Obscurant Grenade

Squad-Layer Drone Manipulation — Hand-Thrown · Pin-Pull · VIS + IR

MS-V generates a dense visual + infrared cloud to break fused FPV/thermal UAS lock when paired with standard visual smoke. Carried in addition to inventory smoke. Employed as 2–3 MS-V + visual smoke against FPV and fiber-optic guided drones.

Status: TRL 2 — Sensitivity study complete (140M samples)

Core vision

Inventory smoke hides you from the eye. Thermal imagers see through AN-M8. Fiber-optic drones don't jam. MS-V adds the IR channel standard smoke lacks — a squad-portable multispectral screen without new launchers or kill chains.

Philosophy: Soldier-first · Complementary to visual smoke · Honest trades · Literature-bound M&S
