The Smart Onboard Data Interface Module (SMODIM) is an integrated device once used by the United States Army and foreign militaries for live simulated weapons training on military platforms. The SMODIM was the primary component of the Longbow Apache Tactical Engagement Simulation System that provides weapons systems training and collective Force-on-Force live training participation.

The Boeing AH-64 Apache is an American twin-turboshaft attack helicopter with a tailwheel-type landing gear and a tandem cockpit for a crew of two. Nose-mounted sensors help acquire targets and provide night vision. It carries a 30 mm (1.18 in) M230 chain gun under its forward fuselage and four hardpoints on stub-wing pylons for armament and stores, typically AGM-114 Hellfire missiles and Hydra 70 rocket pods. Redundant systems help it survive combat damage.
