Military and Technical Summary: Patria_ITO90_FinnArmy
Military Summary (Doctrine and Tactical Role)
Tactical Designation: ITO 90 (Ilmatorjuntaohjus 90 — Surface-to-Air Missile in Finnish), integrated on the Patria Pasi XA-181 (6×6) armored chassis.
Primary Operator: Finnish Army (Maavoimat).
Operational Role: All-weather Short-Range Air Defense (SHORAD) system.
Primary Mission: Protect mobile mechanized units, command posts, and critical infrastructure against attack helicopters, low-altitude aircraft, cruise missiles, and unmanned aerial vehicles (UAVs).
Tactical Capability: Thanks to its self-propelled 6×6 chassis, it provides high cross-country mobility and armor protection against shrapnel and small arms fire, enabling rapid deployment and relocate capabilities (shoot-and-scoot).
