The Inkas Hornet 4x4 can be fitted with a one-man open-top turret mounted on the roof of the vehicle. It can be armed with a 7.62 mm or a 12.7mm machine gun. The turret is fitted with armor plates and bulletproof windows offering protection against small-caliber ammunition at 360°. The gunner position has a retractable step. As an option, it can be equipped with a remotely operated weapon station.

The design of the Inkas Hornet is divided into three main compartments with driver’s and commander’s seats at the front, troops’ compartment in the middle, and cargo compartment at the rear. There are four individual seats at the main crew compartments. Four additional seats can be fitted in the rear cargo compartment. There are two doors on each side of the vehicle, fitted with bulletproof windows protected by a metal mesh guard. Each window is fitted with a round-type gun-port allowing the crew to use individual weapons from inside of the vehicle. The rear of the crew compartment is fitted with a single door with access to the cargo compartment. There are two large bulletproof flat windshields at the front of the crew compartment that can be protected by metal mesh guards, hinged at the top in a normal situation. The cargo body is covered by canvas and its rear panel is closed by one half-door opening laterally. The hull of the vehicle provides Level CEN B6or STANAG Level 2 protection against 7.62x51mm ammunition. The bottom part of the chassis is protected against a simultaneous explosion blast from two DM-51 hand grenades. The filling of DM-51 consists of 60 grams of Nitropenta.
