It looks like a Bell 206 JetRanger that had a bad experience in a body shop: Flat platform tops a massive engine housing; mast-mounted "eyeball" gun sight typical; armament sponsons project below cockpit.

Technically, it's a scout helicopter, but can be armed with air-to-air or air-to-ground missiles, multiple machine guns, all sighted through the mast-mounted television eye, built for normal optical or infrared imaging. Used in the Gulf War, prior to the invasion of Kuwait, to suppress gunboat attacks on oil tankers. Rarer than the Apache or Huey Cobra attack helicopters.
