3 Key Points (Benefits Over Features)

Guarantees

Firefighter Safety: Keeps ground crews at a safe distance from high-risk thermal zones, chemical hazards, and collapsing infrastructure.

Continuous

High-Volume Suppression: Eliminates the strict weight limits of internal payload tanks by anchoring directly to fire engines for infinite water/foam deployment.

Tactical

Force Multiplier: Combines real-time 2MP optical surveillance, window-breaching tactical projectiles, and a 5km megaphone on a single rapid-deploy platform.
