The High Speed Sentry (or HISS) was another example of early vehicles specifically for the Cobra army, enemy of G.I.Joe. Considered a tank, the HISS boasted "double diablo" cannons that swiveled, and held two figures: one in the cockpit, the other manning the cannons. Additional figures could ride on the outside of the HISS tank by pegs that fit into the bottom of their feet.
The HISS came with a generic 'HISS Driver' action figure with filecard, blueprints, sticker sheet and accessories.
Like many of the vehicles in the G.I.Joe line, the body of the HISS was repainted and used several times over in various later releases.
