COBRA possesses a formidable arsenal of weapons and tech. They threaten the skies with Rattlers and COBRA Flight Pods. They terrorize the deeps with Hammerheads. The backbone of their armored military, however, is the ground-based High Speed Sentry, also known as the H.I.S.S. Tank. As COBRA's main battle vehicle against G.I. Joe, they are fast and dangerous, armed with the devastating 90mm twin-barrel Double Diablo Gun.

Drivers of H.I.S.S. Tanks are among the elite of COBRA's recruits. They are picked from amongst the vile throngs that answer COBRA's call for their physical prowess, technical know-how, and absolute dedication to COBRA's evil cause. As mechanical experts, H.I.S.S Tank drivers are adept with many of COBRA's other common vehicles, such as Rattlers or F.A.N.G. Copters.

The H.I.S.S. Tank is available in the Heroscape G.I. Joe: H.I.S.S Tank Army Expansion. Pre-Order now for a March 2027 release!
